Problems solved by technology

Among them, all-terrain vehicles generally have insufficient power under low engine speed conditions; at the same time, since the engine must participate in work under all working conditions, the combustion of the mixture is insufficient during low speed and variable working conditions, resulting in low thermal efficiency and low fuel consumption. High, the content of harmful gases in the exhaust gas is high, and the structure of the engine also restricts its application on all-terrain vehicles

Abstract

The invention discloses an engine and a crankcase thereof. The crankcase comprises a first case body, a second case body, an oil pan and a side cover. The second case body is connected to the lower portion of the first case body, a crankshaft cavity and a crankshaft hole are defined by the second case body and the first case body, the crankshaft cavity is communicated with the crankshaft hole, and the crankshaft hole is formed in one end of the first case body and one end of the second case body. The oil pan is connected to the lower portion of the second case body. The side cover is connected to the other end of the first case body and the other end of the second case body. Therefore, by reasonably arranging the first case body and the second case body, a crankshaft can conveniently extend out of the crankcase to be matched with a rotor so that the crankcase can be suitable for an extended-range power assembly, and is reasonable in overall structural arrangement and high in structural reliability.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine and a crankcase thereof. Background technique [0002] In the related art, the all-terrain vehicle generally adopts a driving mode of a single power source, and the single power source is usually a fuel engine. Among them, all-terrain vehicles generally have insufficient power under low engine speed conditions; at the same time, since the engine must participate in work under all working conditions, the combustion of the mixture is insufficient during low speed and variable working conditions, resulting in low thermal efficiency and low fuel consumption. High, high content of harmful gases in the exhaust, and the structure of the engine also restricts its application on all-terrain vehicles. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the presen...
