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.
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.
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.
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.
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.
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.
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 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.
You will need
- - screwdriver;
- - cleaner engines;
- a piece of aluminium with a thickness of 1 mm or cans of beer;
- - metal shears;
- - sharp knife.
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.
Remove the EGR valve vacuum hose. Unscrew the bolts of the housing. Remove the valve and gasket. Clean the valve body with engine cleaner.
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.
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.
Install plug, check the valve EGR in place, fasten the bolts.
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.
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.
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.
It is believed that after installing the plug in this valve the car must not be subjected to excessive loads at the maximum gear.
