Title: Method for cyclically disabling cylinders of v-type diesel engine
Inventor: LI YOUFENG
IPC: F02D17/02
Filed: 2017-12-04
Abstract: A method for cyclically disabling cylinders of a V-type diesel engine. For example, if all cylinders are sequentially ignited once in a range of m degrees in which a crankshaft rotates, and it is assumed that the number of cylinders is n: n/2 cylinders are ignited in the first m/2 degrees working cycle, and the other n/2 cylinders are ignited in the second m/2 degrees working cycle. When the method is applied to a working cycle of a normal four-stroke diesel engine, half of the cylinders stop working, thereby improving combustion, reducing fuel consumption, and preventing a supercharger exhaust pipe from spraying oil. When a diesel engine is running in an idle state, by disabling some of the cylinders such that the amount of diesel injected into a single working cylinder is increased, diesel injection control precision and atomization performance of a single cylinder is improved, thereby improving combustion, reducing fuel consumption and emissions, and solving the problem of exhaust pipes spraying oil.
