Abstract

The two pistons per cylinder internal combustion engine has two pistons (p) per cylinder ,which are forced in opposite directions by a charge induced though valve (v). Crankshaft gears (a) and (c) are driven by the pistons, which inturn drive flywheel (b). Flywheel (b) provides drive to the engines gearbox and also keeps both sides of the engine in time with each other.

Description

2359336 -I- TWO PISTONS PER CYLINDER INTERNAL COMBUSTION ENGINE.
The invention relates to a two pistons per cylinder internal combustion engine.
Internal combustion engines are well knownhaving the form of pistons been driven by a charge of fuel and air igniting thus forceing the pison to move. All current internal combustion engines have one piston per cylinder driven by one charge of fuel.
However internal combustion engines are relatively inefficient due to the fact that when the piston is at the bottom of the stroke there is still a great amount of energy left in the cylinder which is unused.
The new invention of the two pistons per cylinder engine,has two pistons per cylinder driven by the same single charge and acting in opposite directions. This extracts more energy per charge than a standerd engine thus improving power and efficiency. Also due to the fact that the forces and momentum from one side of the engine are matched equally by the other, the engine will run more smoothly than a conventional engine.
Refering to the plan view FIG. 1 and side elevation FIG.2 The pistons (p) are forced in opposite directions by a charge induced through valve (v). Each piston drives a crankshaft one connected to gear (a) and one to gear (c). Gears (a) and (c) drive flywheel (b) which provides drive to a gearbox and also keeps both pistons in time with each other. Pulleys (d) and (c) provide drive for the camshaft and alternator. In order to maximise efficiency the induction valves should be closed halfway through the induction stroke, this would keep the amount of charge drawn into the cylinders comparible with and engine of half the capacity.

Claims (2)

1. An engine with two pistons per cylinder.
2. An engine as claimed in 1 wherein the force used to drive both pistons is provided by the same single charge.
