What contemporary car outfit uses derv motor is increasing, and difference of the function of derv engine hiemal that start is a difficult problem that drivers face. Accordingly, the starting character of derv engine, skill that start, how be being started smoothly is a car advocate the main mastery of a skill or technique that should master.
Freezing season should undertake warm-up
Derv engine is when cold start-up, because of cannot obtaining diesel oil press the main reason that lighting temperature is the influence function that start. To this, can adding hot water engine to cool is warm-up, this is the efficient way that improves the performance that start. Particular way is: Add hot water continuously (let current give cylinder body) , raise warm-up of travel of water Wen Jin gradually. Shut again when the water temperature that should pour out of is higher turn on the water switch. In addition, the bright fire such as usable blowtorch undertakes heating to oily base case, in order to improve the performance of going from place to place of engine oil, in order to reduce the athletic resistance of parts.
Improve the sealed performance of cylinder
One of distinction of diesel engine and gasoline engine are pressed namely light type, because this requirement cylinder is due higher sealed performance. When engine of winter cold start-up, because piston annulus and cylinder are mural engine oil is very few, sealed effect not beautiful, can appear to be started repeatedly and cannot catch fire locomotive phenomenon. Because cylinder wears away,affect the sealed performance of cylinder heavier and badly sometimes, it is more difficult to make start. To this, can tear open fuel injector below, every add engine oil of 30 ～ 40ml inside the crock, in order to enhance the sealed performance of cylinder, increase the pressure when compressing.
Remove the air in oil path
The deflate bolt on oil pump of unscrew high pressure, the pump that use a hand is oily in order to discharge the air in clean low-pressure oil path; Next, discharge the air in high-pressured oil path again clean. Specific means is: Unscrew the oily pipe fittings on each fuel injector, make accelerator lies the largest position that offer oil, rotational crankshaft, go out till connect of vitta of each crocks of fuel injector till oil is short.
Of course, of derv choose the performance of going from place to place when should assuring air temperature of lowest of car travel area, otherwise, will choose because of derv undeserved, affect its flow performance and appear the difficulty that start. Additional, winter still should assure the capacity with sufficient accumulator and good performance, this also conduces to those who improve diesel engine starting function.
Engine hiemal is started, exquisite quite much, should insist to shake first normally turn crankshaft, the restart after making its movement light. A few kinds of afore-mentioned methods, answer to be chosen in the light of particular case individual event, also but multinomial choose at the same time, car advocate the friend mights as well try with one's own hands, regular meeting makes the diesel engine that starts difficulty originally is started easily.
