A fluid as virtual piston to secondary compression for ICE

[Category : - Motors]
[Viewed 168 times]

The invention relates a system for an internal combustion engine using a fluid as a virtual fast piston with variable stroke. This system enables the engine to behave like a variable compression ratio engine. It consists of a duct relatively long and narrow serving as a cylinder for the virtual piston and opening into a valve. This duct is an extension of the clearance volume in the cylinder head of the engine. When the piston arrive near to the top dead centre, a second compression of the air/fuel mixture is carried out by introducing a fluid at high-pressure via a valve. The introduction of fluid in a duct is manifested as a jet of fluid without mixing with the air/fuel mixture. This system allows regardless of the load, to regulate the pressure at the ignition of combustion and to increase the quantity of matter in the cylinder, despite the air/fuel mixture is close to stochiometric proportions.

The present invention improves the overall energy efficiency of the engine and limits the polluting emissions produced without modifying the general structure and the operation of the internal combustion engine, by the following characteristics:
- Converting a more heat energy of combustion into mechanical work.
- Generating a more optimal pressure and temperature for the combustion for any type of an internal combustion engines, regardless of the load. rn- Recovering part of the heat energy of the exhaust gases. rn- Recovering part of the kinetic energy during braking.
- Saving part of the mechanical work required to the compression.
- Decreasing the temperature peak of combustion.
- Ignition of the combustion by a compression for HCCI engines. - Controlling the moment of auto-ignition for HCCI engines.
- Operating the Diesel and HCCI engines with a proportion that are less lean and close to stoichiometry.
