The invention discloses a piston cooling injection system. The piston cooling injection system comprises a main oil way, a secondary oil way, a first control oil way, a second control oil way, a collecting channel, an oil injection mechanism, thermosensitive control mechanisms, a first connecting oil way, a second connecting oil way and a secondary oil way connecting oil way; the main oil channelcommunicates with the first control oil way through the first connecting oil way; the main oil way communicates with the second control oil way through the second connecting oil way; the second control oil way and the first control oil way communicate with the collecting oil way; the collecting oil way communicates to the secondary oil way; the oil injection mechanism communicates with the secondary oil way; and the thermosensitive control mechanisms are arranged in the first control oil way and the second control oil way. Two thermosensitive control mechanisms are provided, are fixed in the first control oil way and the second control oil way, and are arranged in the oil channel in parallel. When one way is broken down to cause closing of the oil channel, the other way is standby, so thatsafe and reliable cooling of pistons is guaranteed.
Description
Technical field [0001] The invention relates to the technical field of engines, in particular to a piston cooling injection system. Background technique [0002] With the technological trend of supercharging and miniaturization, the specific power of automobile engines has become larger and larger, and the heat load of the combustion chamber has increased. Therefore, forced injection cooling of the piston in the engine has become a standard solution. [0003] But the cooling capacity of the piston can neither be insufficient nor excessive. Insufficient cooling will cause the piston head to melt and knock; excessive cooling will lose thermal efficiency, reduce the viscosity of lubricating oil and increase friction loss. The ideal piston cooling injection system should be based on the demand for timely and appropriate cooling, high reliability, and consideration of cost performance. [0004] At present, the most commonly used technical solution is based on pressure control. A pressu...
