Fuel saving device for six-cylinder diesel automobile engine

Abstract

A fuel saving device for a six-cylinder diesel automobile engine belongs to the technical field of diesel automobile engines, and can solve the problem of fuel economy of automobile running. The fuel saving device includes a fuel injection pump and fuel pipelines which connect the fuel injection pump and all the air cylinder combustors, and is characterized in that: solenoid valves corresponding to the fuel pipelines are connected to the fuel pipelines connecting the fuel injection pump and a first cylinder and / or a sixth cylinder combustor in series; control buttons of the solenoid valves are arranged in a position where a driver can easily operate the control buttons. The fuel saving device can allow all the air cylinders or a part of the six air cylinders to work according to the load of the engine; under the premise of ensuring stable running of the engine, the fuel can be saved, the operation benefits can be increased; and the fuel saving device can be applied to a cargo diesel automobile during running at a high speed.

Description

technical field [0001] The invention belongs to the technical field of diesel automobile engines, in particular to a fuel-saving device for a six-cylinder diesel automobile engine. Background technique [0002] The working process of a diesel engine is the same as that of a gasoline engine. Each working cycle also goes through four strokes of intake, compression, power, and exhaust. However, since the fuel used in the diesel engine is diesel oil, its viscosity is higher than that of gasoline, it is not easy to evaporate, and its auto-ignition temperature is lower than that of gasoline, so the formation and ignition of combustible mixtures are different from those of gasoline engines. [0003] Diesel engines inhale pure air during the intake stroke. When the compression stroke is close to the end, the diesel oil is raised to above 10MPa through the fuel injection pump, and the high-pressure fuel pump delivers the diesel oil to the fuel chamber of each cylinder, where it is m...

AI Technical Summary

Problems solved by technology

At this time, if the six cylinders still continue to work, there will inevitably be excess engine power and high fuel consumption, which will increase the actual problem of transportation costs

In order to solve the problem of transportation costs, drivers often use methods such as gliding in neutral, gliding with the engine off, which brings hidden dangers to driving safety.
