Abstract

The invention relates to a range extender engine structure, comprising a crankcase part, a cylinder body part and a cylinder head, the crankcase part includes a left crankcase cover and a right crankcase cover, and the left crankcase cover includes a left crankcase cover body and a set of An integrated oil supply structure on the left crankcase cover body, the right crankcase cover includes a right crankcase cover body and a bearing support seat arranged on the right crankcase cover body; the cylinder body includes a cold water cavity, a sealing cover and a The cylinder liner in the cold water cavity; the engine mechanism is also provided with a chain-type air distribution device, including a crankshaft sprocket, a timing chain, a camshaft combination device, a chain tensioning device and a rocker arm. The range extender engine structure of the present invention can effectively solve the problems of crankshaft breakage and oil leakage of the existing range extender; the inner cooling fins and the large-capacity water storage space arranged in the cold water cavity can achieve better heat dissipation effect; The top-mounted gas distribution structure can greatly improve the running stability of the range extender, making the range extender engine lower in fuel consumption and longer in service life.

Description

technical field [0001] The invention belongs to the field of range extender engines, in particular to a structure of a range extender engine. Background technique [0002] A range extender usually refers to a kinetic energy device that can provide additional electric energy to help electric vehicles or electric equipment extend the running time. Ordinary range extenders are usually composed of an engine and a generator; the engine part of the range extender is different from the The fuel engine used alone is especially limited by the volume and weight and the use environment. The range extender engine generally has a small displacement and low power, which is different from ordinary fuel engines in structure and function. The common range extender engines on the market mainly have the following problems: [0003] 1. The crankshaft of ordinary range extenders is only supported by a single bearing, which is easy to break. At the same time, because the dynamic balance of the...
