Multi-fuel electronic injection engine for forklift

Abstract

The invention relates to the field of forklift engines, in particular to a multi-fuel electronic injection engine for a forklift.The multi-fuel electronic injection engine comprises a fuel feeding system for feeding gasoline or natural gas to an engine cylinder combustion chamber and an electronic control system for controlling feeding of gasoline and feeding of natural gas fuel to the engine.When the gasoline is fed, a corresponding gasoline nozzle is opened, meanwhile, a corresponding ignition coil of the cylinder combustion chamber starts to ignite, and air synchronous with injection gasoline enters an electronic throttle valve, and then enters the cylinder combustion chamber through an air intake manifold to allow the engine to operate; when gas is fed, a corresponding gas nozzle is opened, meanwhile, a corresponding ignition coil of the cylinder combustion chamber starts to ignite, and air synchronous with injection gas enters the electronic throttle valve, and then enters the cylinder combustion chamber through the air intake manifold to allow the engine to operate; the electronic throttle valve is arranged on the air intake manifold, adjusts the opening degree of a speed-limiting throttle valve body and limits the opening speed of the throttle valve body.

Description

technical field [0001] The invention relates to the field of forklift engines, in particular to a multi-fuel electric injection engine for forklifts. Background technique [0002] Forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. Widely used in various fields such as stations, ports, airports, factories, warehouses, etc. [0003] There are four main types of existing forklift engines: diesel engines, carburetor gasoline engines, electronic injection natural gas engines, and multi-fuel mechanical superposition engines. The first three types are common single-fuel forklift engines, while multi-fuel mechanical superposition engines have only been applied to forklifts in recent years. The main principle is to combine gasoline (or liquefied petroleum gas) and natural gas The fuel is applied to the engine to achieve the function that the forklift...

AI Technical Summary

Problems solved by technology

Moreover, the current technical state of domestic forklifts with multi-fuel EFI engines with a maximum speed of 4600rpm and a torque of 196N.m cannot meet the requirements of forklift working conditions.
