In order to overcome the serious mechanical vibration in the existed single-cylinder four-stroke free-piston generator, a novel opposed-piston four-stroke free-piston generator is designed and simulat....
In this paper, a new-type balanced opposed-piston two-stroke (OP2S) gasoline direct injection (GDI) engine is developed by Beijing Institute of Technology. OP2S-GDI engine has some potential advantage....
When designing a new internal combustion engine, the choice of technology for the timing drive system is one of the key decisions that determines the overall characteristics of the engine with far rea....
A recent trend in high-pressure gasoline pumps is increasing the outlet pressure. One of the most important topics for increasing this pressure is improving volumetric efficiency. Therefore, the purpo....
General Motors has developed an all-new Ecotec 1.5 L range extender engine for use in the 2016 next generation Voltec propulsion system. This engine is part of a new Ecotec family of small displacemen....
The spark ignition circuit inside an internal combustion engine system is the source which provides the initiation energy required for triggering combustion in a spark ignition (SI) engine in-cylinder....
In the current state of the art automotive fuel pumps there is only one channel on each side of the impeller. For high flow and pressure applications the size of such pumps becomes excessive. In order....
A comprehensive investigation on the impact of piston design on scavenging and combustion in an opposed- piston, opposed-cylinder (OPOC) two-stroke engine is carried out and presented in this paper. T....
Toyota Motor Corporation is developing a series of engines belonging to its ESTEC (Economy with Superior Thermal Efficient Combustion) development concept. This paper describes the development of 8NR-....
A high-pressure fuel pump in a GDI (Gasoline Direct Injection) engine has been increasingly applied on passenger vehicles because of its high fuel efficiency and reduction of exhaust emissions. The de....
