Abstract

The invention discloses a slide valve air valve type gasoline engine with opposed pistons. The slide valve air valve type gasoline engine comprises a cylinder sleeve, an opposed crankshaft connectingrod mechanism and a slide valve air valve type gas distributing mechanism. An air inlet and an exhaust port are formed in the middle of the cylinder sleeve, and the air inlet and the exhaust port arecontrolled by the slide valve type gas distributing mechanism to open and close. The opposed crankshaft connecting rod mechanism is in gear transmission or in cog belt transmission, so that power confluences of crankshafts on two sides and synchronous movement of the piston on the air inlet side and the piston on the exhaust side are achieved. By adopting a four-stroke working mode, opening and closing of the air inlet and exhaust port are controlled by air inlet and exhaust side slide valve mechanisms; the opposed pistons adopt the same flat top structural design; and a sparking plug and an oil atomizer mounting hole are designed in the side wall of the cylinder sleeve in the middle of the cylinder sleeve and form an included angle of 30 degrees. The slide valve air valve type gasoline engine disclosed by the invention has the advantages that 1) a four-stroke working mode of the gasoline engine with the opposed pistons can be achieved; 2) the inflating efficiency is improved by optimizing the movement rule of the slide valve; and 3) fuel consumption rate and consumption are reduced at the same time.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a sliding valve valve type opposed-piston gasoline engine, which adopts an opposed-piston four-stroke working mode and a fuel injection mode of direct injection in a cylinder. Background technique [0002] It has been more than 100 years since the advent of the internal combustion engine. The modern internal combustion engine has changed its structure and performance, but it is still developing and improving. The current development of the internal combustion engine industry is mainly centered on energy saving, fully taking into account the requirements of emissions and reliability, so as to achieve an overall improvement in the performance of internal combustion engines. The petroleum fuel consumed by internal combustion engines accounts for more than 60% of the total oil consumption, while almost 50% of the CO, HC and NOx emissions from the combu...
