Advice 1: How to drown diesel

On gasoline engines the motor is switched off by turning off the ignition system. On dieseltion of the ignition system there, so they jammed differently. And to extend the life of diesel, should know and follow a few rules when the engine is off.
How to drown diesel
Instruction
1
To drown out the diesel engine, close the fuel supply. On passenger cars this put the key in the ignition in the desired position. In this work the electric valve blocking the flow of diesel fuel at the fuel rail. On current models stops the supply of control pulses to the opening of the injectors.
2
In trucks, large buses, and tractors click the button on the floor in the foot area of the driver or on the dashboard, or on a special lever. A mechanical drive will block the flow of fuel in the fuel pump. Keep in mind that just a click is not enough. After you hold it until then, while diesel will not be muted.
3
To use the device for shutoff of the fuel supply as the engine brake on a truck or bus, diesel stop them without turning off the clutch. The car will start to slow down. Use this technique when approaching traffic lights or on downhill and only truck (bus), equipped with a mechanical drive of shut-off valves. On cars with valve the use of this method may lead to breakage of the power system.
4
In case of failure of electric valve, blocking the flow of diesel oil, use the following trick to kill the motor without turning off the transmission, release the clutch while pressing the brake. For greater efficiency of this technique in advance turn on high gear.
5
When operating the diesel engine at low temperatures (-25 and below) before stopping the diesel, fill the oil sump a glass of gasoline. Gasoline will temporarily reduce the viscosity and facilitate the start-up. After starting and engine warm-up gasoline to evaporate, and will evaporate through the crankcase ventilation. After the active use of this method at the end of the winter, change the oil, since gasoline accelerates oxidation of the oil.
6
Wait 1-3 minutes before shutting down the diesel, allowing it to work at idle. This will significantly increase the service life of the turbine, allowing the oil to cool down and to cool and to drain out of the turbocharger before shutting down. Of course, for diesel engines not equipped with turbocharging in the application of this method there is no need.
7
On modern diesel cars nominally set turbotimer providing compulsory work diesel for some time after its shutdown. Turbotimer with intelligent control system calculates the necessary time after which the motor will be suppressed, given the duration and intensity of stress on him.

Advice 2: How to install diesel for Gazelle

The popularity of diesel engines is not surprising: they are economical, they have high torque, and the cost of diesel fuel remains available. Currently the engines are mounted on different cars, including the Gazelle.
How to install diesel for Gazelle
You will need
  • - diesel engine;
  • - the lifting mechanism;
  • - engine oil
  • tools.
Instruction
1
Before starting a diesel engine on a Gazelle, to study its structural features. Of course, at first glance, the differences between diesel and gasoline engines not relevant: the same pistons, cylinders and connecting rods. However, in a diesel engine is somewhat reinforced valve parts. Due to this, diesel is able to withstand a higher load than the gasoline engine.
2
Please note that in a diesel engine the air and fuel is performed separately. First cylinder receives compressed air and only after it is heated to 700-800 degrees, the combustion chamber is fed under high pressure fuel.
3
After examining the features of diesel, continue to practice, you install the engine on a Gazelle. This process differs little from installation of diesel engine cars of other brands. First of all with the lifting mechanism, install the diesel in the engine compartment, and first of all have to enter gear housing.
4
Lubricate all fasteners with engine oil, then install them in the slots and tighten. Lower the power unit to the seat reserved for him. Please note: all guides power unit should be placed in special recesses.
5
After removing the diesel from the lifting mechanism into the body of a Gazelle of a wire to ground, then check the selector mechanism of the gearbox. Then connect the sensor wiring speedometer and reverse.
Note
The noise of the diesel is not a reason to panic! Increased noise due to the pressure increase in the cylinder of a diesel engine.
Useful advice
System pre-heating ensures that the cold start of the diesel engine. To this end, in the combustion chamber are mounted electrical heating elements, i.e. glow plugs. As soon as the ignition comes on, the heating elements within a few seconds, heats up to 800-900 degrees, thereby accelerating warming of air and spontaneous combustion of diesel fuel.

Advice 3: How to drown out the EGR valve

The exhaust gas recirculation system (EGR) is designed to reduce the content of nitrogen oxides in the exhaust gases of the vehicle. After contamination and failure of valve EGR , the car may stall at idle, to consume more fuel. In order not to waste time and money to repair this system, you can simply switch off the valve.
How to drown out the EGR valve
You will need
  • - screwdriver;
  • - cleaner engines;
  • a piece of aluminium with a thickness of 1 mm or cans of beer;
  • - metal shears;
  • - sharp knife.
Instruction
1
Remove the cap of the expansion tank and drain plug in the lower right corner of the radiator. Drain the antifreeze into a container. Can be adapted for these purposes, a five-liter plastic bottle with the top cut off. Disconnect the hose to the antifreeze.
2
Remove the EGR valve vacuum hose. Unscrew the bolts of the housing. Remove the valve and gasket. Clean the valve body with engine cleaner.
3
Take the plug out of a piece of aluminium with a thickness of about 1 mm. If it is not at hand, the cover can be made of cut beer cans. Paronite is better not to use, as it burns quickly.
4
Use factory valve gasket EGR as a template. Put it on the tin and "circle" with a sharp knife. After that the plug is easily cut with scissors. Punch holes in it for bolts.
5
Install plug, check the valve EGR in place, fasten the bolts.
6
Clean and remove the valve from the intake manifold. Clean the manifold and install the valve into place, reconnect all the hoses. Fill with antifreeze, do not forget to measure its level.
7
Alternatively, remove the valve, put instead a steel plug, turned the size of his hole. After installing the plug valve on your onboard computer will pop up an error (of course, if this block is not sewn with the shutdown indications on the system of the usr). If necessary, refer to specialists for its firmware or just disconnect the terminal from the sensor.
Note
The main reason for the failure of the EGR valve is defective gasoline. Sensor the EGR system in case of failure of the valve can not be repaired and will require replacement. So, if you decided to drown out the EGR valve, it's better to do without waiting for the moment when its contamination and breakage will cause other malfunctions in the car.
Useful advice
It is believed that after installing the plug in this valve the car must not be subjected to excessive loads at the maximum gear.

Advice 4: How to choose diesel

Japanese cars with diesel engine delight their owners good performance, fuel efficiency, reliability and ease of repair when operating in the conditions of Russian roads. To get all these advantages buying diesel, it is important, adhering to the simple rules, make the right choice.
How to choose diesel
Instruction
1
Buying a diesel car from a stranger, put the engine a thorough check. Make sure that when you run the engine was cold. Serviceable diesel plants with a twist. Please note that the cold he emits a pretty noticeable noise. Then start the engine is warmed up, the noise should significantly subside. If in this state it won't start immediately, but only after 3 to 9 attempts, so worn rings, piston.
2
Check whether belching from the exhaust smoke when you press down on the accelerator when the engine is warm. If a cloud of dark smoke, it is likely, wear has undergone a oil ring or a faulty injector. White smoke indicates fuel getting into the water. Put under the exhaust a sheet of paper. If it appeared soot, so the fuel is not burned completely.
3
The sound of the engine should be soft, uniform, no knocks. Reverse the evidence of irregularities in the operation of the valves. Try to recognise the noises in the set and reset speed, to determine the operation of the crankshaft and piston. Open the oil cap. Indication of what is happening somewhere blowby are the oil spray from the oil fill neck.
4
Look under the hood. Determine the integrity of the cylinder block and nuts to the injectors. Traces of white or red sealant instead of black indicate that the engine's been opened. All the bolts that fix the auxiliary devices must be in place.
5
To assess the condition of the ear, run the car, switch off and then switch on the ignition. Light oil pressure switch should light up in 2-3 seconds, but not before.
6
If the results of all these actions, you are not disappointed and you are ready to become the owner of a diesel engine, measure the compression and crankcase pressure, check injectors, cooling system.

Advice 5: How to choose a diesel car

Buying a diesel car for the uninitiated – it is complex, dark and obscure. Therefore, you should know how to choose a diesel car, to avoid disappointment from buying.
How to choose a diesel car
You will need
  • Level meter compression gauge pressure of the crankcase gases and other equipment for engine diagnostics.
Instruction
1
You should first check how the engine starts in a cold condition. This is best done in the morning, so engine was cold. Serviceable diesel will start with a half-turn. If not start immediately - this is a bad sign (wear or piston rings). The cold will be significantly noisy, warm – much quieter. If you have a hot engine, on many models the heating of engage will not, and the start will occur due to the compression.
When you press on the gas pedal to warm the engine, check to see whether the smoke belching from the exhaust pipe. If the smoke is dark, so there is a wear oil ring problems or injector. White smoke means water in the fuel. Commonly used method: a white handkerchief or sheet of paper put under the exhaust. The presence of soot on the paper or fabric indicates increased consumption of oil or incomplete combustion. The turbo allowed the black smoke to power turbines, as well as when blipping. But it needs to be short and not thick. Should try the engine without the air filter. Maybe a clogged filter is the cause of increased opacity.
2
Irregular, tapping sound in engine performance indicates that the adjustment of the valves, and possibly, problems with the valves or piston. "Hard" sound in combination with the black smoke at high rpm means the early injection angle. Interruptions and grey smoke at idle in combination with shortages and black smoke at high – a late injection angle. A rough running diesel at idle in combination with the black smoke reveals the non-working injector. To test this, disable it. The engine will work gently.
Opening the oil cap, check no oil spray from the oil fill neck. Their presence is an indicator of blowby. The reasons for this can be many.
You should evaluate the General appearance of the engine compartment. If the nuts on the injectors and cylinder block are free of nicks, if traces of white or red sealant (black, from Japanese cars), so the engine has not been opened. You also need to check mounting bolts on all accessory devices. The condition of the ear is tested this way: to warm up the car, and immediately turn the ignition on. The oil pressure indicator should light up in 2-3 seconds. If before – liners should be changed.
3
Compression
At the station or in the garage equipped to measure compression. Compression should be at least 25. However, this value can be different for each engine size. The variation should not exceed 0.5 for a new car and 1-2 old. A large spread indicates a future overhaul. Low compression can be due to wear of the piston or worn valves. Wear of valve repair cheaper and easier.
4
Injector
The injector when the work needs to emit a characteristic sound and spraying the fuel in dusty condition. Spraying in the form of drops and jets is absolutely contraindicated the engine. With the injectors, you should evaluate the hoses for leaks fuel flow and reverse flow.
5
Oil
The color of the oil should be black, without impurities. Silver-grey shade of the color of oil indicates a recent use of molybdenum additives.
6
Cooling system
You should verify the absence of bubbles on a warm engine at medium and high rpm. Metal piping should be free of rust and red plaque (a sign that the engine was overheating).
7
The last step is the measurement of the pressure of crankcase gases. The high value of this indicator can only be due to worn piston or valves.
Note
Finding fault in choosing a car, you first need to assess the prospects of repair of these problems. And only then make a decision: to abandon the purchase of the car or bring down the price.
Useful advice
It is impossible to inform the seller on how and what you will test. He can "take action" and to hide problems of the vehicle sold.
