Abstract

The present invention relates to a new horizontal diesel engine body, especially a horizontal single-cylinder or double-cylinder diesel engine body employing gantry structure, which belongs to field of diesel engine. Wherein, the front end of horizontal gantry single or twin cylinder diesel engine is a cylinder, the back end is a gantry globoidal crankcase, the left end is a flywheel end and related mounting surface, the right end is a gear chamber surface and related accessory mounting surface, the top end is a mounting surface of the gasoline tank, the bottom is an oil pan mounting surface and a cooling water chamber, five oil channels are provided in the engine body, the specific compulsory cooling water chamber is provided outside the cylinder cooling water cover (namely between handspike and oil pan mounting surface) on bottom of engine body, a reinforce rib is provided on engine body. The gantry horizontal diesel engine body employs a gantry type globoidal crankcase, the cover of crankcase and the engine body respectively are single part, the crankcase cover of the engine body and the crankcase are connected at mounting surface of the crankcase cover by a bolt. The present invention has merits of compact structure, good intension and rigidity, high carrying capacity of headstock, good reliability, good cooling efficiency because of cooling water chamber on bottom of engine body, short oil channels, good lubrication efficiency and low cost.

Description

technical field [0001] The invention relates to a new-generation horizontal single- and double-cylinder diesel engine body, in particular to a horizontal single- and double-cylinder diesel engine body with a gantry structure. It belongs to the field of diesel engines. Background technique [0002] The diesel engine body constitutes the skeleton of the diesel engine. All the main parts and accessories of the internal combustion engine are installed inside and outside the body, which is the most critical part of the diesel engine. In terms of structural design, on the one hand, it is necessary to ensure that the body has sufficient strength and rigidity; on the other hand, it is necessary to ensure that the structure of the body is reasonably arranged, compact, and light in weight. The rationality of its structural design directly affects the power, economy, reliability and emission performance indicators of the diesel engine. Chinese patent CN2423417 discloses a horizontal ...
