Direct-spraying type engine

Abstract

The invention belongs to the engine manufacturing technical field, in particular relating to a direct injection engine for injecting water and oil into a cylinder. The invention provides a direct injection engine, which comprises the cylinder, a combustion chamber, a water supply device, an oil supply device and an electronic control system which can simultaneously perform water injection and oil injection, wherein, a gas inlet valve, a gas outlet valve and a spark plug are respectively arranged above the combustion chamber; a water nozzle and an oil nozzle which are electrically connected with the electronic control system are respectively arranged on the cylinder; the water nozzle and the oil nozzle are arranged oppositely; and the water supply device and the oil supply device are respectively communicated with the water nozzle and the oil nozzle. Compared with the prior art, the direct injection engine not only can realize fuller combustion of oil, save the fuel oil and prolong the service life of the engine but also can reduce the pollutants in the exhaust gas exhausted by the cylinder and play a part in environmental protection.

Description

technical field [0001] The invention belongs to the technical field of engine manufacturing, in particular to a direct-injection engine that injects water and oil into a cylinder. Background technique [0002] With the continuous development of technology, direct-injection engines have already become well-known industrial products, and are widely used in various types of vehicles such as automobiles and ships, and are also used in other fields, such as diesel power stations. At present, there are direct-injection gasoline engines that directly inject the mixture of water and oil into the cylinders on the market, but the economic benefits of this product are very low. Because in order to make the mixture of water and oil have considerable stability, special additives must be used, and special electromechanical equipment must be added to prepare this additive, which not only makes the production and use of the engine more complicated, but also increases the The cost of purcha...

AI Technical Summary

Problems solved by technology

[0004] This technology mainly has the following defects: First, because the water and oil injected into the cylinder are carried out alternately, this will inevitably lead to the oil being unable to burn evenly; Evenly spread, which leads to the incomplete combustion of gasoline, which not only wastes oil, but also pollutes the environment with exhaust gas generated after combustion
