Abstract

The invention discloses a multi-cylinder engine oil supply method and a pump truck engine oil supply method and system. According to the multi-cylinder engine oil supply method, when the output power and output torque requirement of a multi-cylinder engine is smaller than the set threshold value or the multi-cylinder engine is in the low output power and low output torque working mode, oil is supplied to part of cylinders of the multi-cylinder engine. According to the technical scheme, the multi-cylinder engine runs under the low-power and low-torque working condition, one or more cylinders are closed, and therefore the multi-cylinder engine can run with few cylinders; and use of fuel can be saved, and the service life of a corresponding oil spraying device and the cylinders can be prolonged.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a multi-cylinder engine oil supply method, a pump truck engine oil supply method and a system. Background technique [0002] With the development of technology, the requirements for engine power and torque are increasing day by day. For example, the improvement of the pumping capacity of concrete pump trucks (hereinafter referred to as pump trucks) requires the engines used in them to have greater power and torque. Correspondingly, the use of multi-cylinder engines is becoming more and more extensive, and the number of cylinders of the engine has been developed from the original 3 and 4 cylinders to 6 cylinders, 8 cylinders and even more cylinders. Generally, 8-cylinder engines have higher rated power and torque than 4- and 6-cylinder engines. [0003] In the prior art, if under certain operating conditions of the engine, the torque and power requirements for the engine are smal...
