Embodiment Construction

[0033] figure 1 A schematic diagram of a spark ignition engine 200 comprising an air intake system 10 according to the invention is shown. Spark ignition engine 200 includes combustion chamber 202 including piston 206 connected to crankshaft 210 by piston rod 208 . The spark ignition engine 200 further includes a spark plug 204 that provides a spark that ignites the air-fuel mixture and thereby applies force to a piston 206 that moves away from the spark plug 204 . Movement of the piston 206 is translated into rotational movement of the crankshaft 210 via the piston rod 208 .

[0034] Known spark ignition engines typically include a three way catalytic converter (not shown) to reduce carbon monoxide and nitrogen monoxide emissions from the spark ignition engine. To function properly, the catalytic converter requires a substantially constant air-to-fuel ratio of approximately 14.7:1. Engine power in known spark ignition engines is typically regulated by regulating air mass ...

Abstract

The invention relates to an air-inlet system (10), and relates to an air-conditioning system (100, 101 ) and an internal combustion engine (200) comprising the air-inlet system. The air-inlet system comprises an air intake port (20), an air output port (30) and a turbine (40) for controlling air mass flow into a combustion chamber (202) of an internal combustion engine. The turbine is provided with a propeller hub (42) which comprises at least one blade (44). The propeller hub is arranged between the air intake port and the air output port for propelling the blade of the turbine. The turbine has an air-flow resistance for determining the air mass flow into the combustion chamber. The effect of the air-inlet system according to the invention is that the use of a turbine enables to use at least some of the pressure drop across the turbine to drive the blade of the turbine for generating rotational energy.

Description

technical field [0001] The invention relates to an air intake system for an internal combustion engine. [0002] The invention further relates to an air conditioning system comprising such an air intake system, to a combustion engine comprising such an air intake system, and to a vehicle comprising such an air intake system. Background technique [0003] Known internal combustion engines regulate engine power by regulating the mass flow of air admitted into the cylinders of the engine. Especially in spark ignition engines where the fuel-to-air mass ratio should be substantially constant, the engine power is adjusted by adjusting the air mass flow into the cylinders. In practice, the air-fuel mass ratio, which is a prerequisite for proper operation of the installed three-way catalytic converter, should be substantially fixed at about 14.7:1. Since the volume of air flowing into a cylinder is constant each stroke - depending on the volume of the cylinder - the air mass flow ...
