The invention provides an engine and a vehicle with the same. The engine comprises a plurality of air cylinders, an oil supply system and a valve, wherein the air cylinders are at least divided into a cylinder deactivation air cylinder region and a cylinder non-deactivation air cylinder region, the oil supply system comprises an oil storage tank, an engine oil pump and a main oil way, the engine oil pump is connected to the portion between the oil storage tank and the main oil way, the main oil way comprises a cylinder deactivation main oil way and a cylinder non-deactivation main oil way, the cylinder deactivation main oil way corresponds to the cylinder deactivation air cylinder region and is used for supplying oil to a kinematic pair of the cylinder deactivation air cylinder region, the cylinder non-deactivation main oil way corresponds to the cylinder non-deactivation air cylinder region and is used for supplying oil to a kinematic pair of the cylinder non-deactivation air cylinder region, and the valve is arranged between the cylinder deactivation main oil way and the cylinder non-deactivation main oil way and used for connecting or disconnecting the cylinder deactivation main oil way and the cylinder non-deactivation main oil way. By arranging the valve, lubricating oil can enter the moving kinematic pairs, the oil temperature increasing speed of the lubricating oil can be high, the kinematic pair lubricating effect of the lubricating oil can be enhanced, the service life of the kinematic pairs can be prolonged, and the performance of an engine can be improved.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to an engine and a vehicle with the engine. Background technique [0002] In the cylinder deactivation technology, when the engine is cold started, single cylinder or some pistons are running, the moving parts need less lubrication and oil change, and the lubricating oil in the oil pan has low temperature and high viscosity. Parts are lubricated, the amount of oil is large, the path is long, the heat generated by the engine during cold start is difficult to heat the lubricating oil quickly, and the temperature of the lubricating oil rises slowly. Even the current dual-chamber oil pan technology can only partially improve the performance. Contents of the invention [0003] In view of this, the present invention aims to provide an engine to solve the problem of poor lubricating effect of lubricating oil when the engine is cold started. [0004] In order to achieve the above object,...
