Abstract
An internal combustion engine enabling asymmetric port timing has an engine mechanism including a crankshaft having a crankpin to which each piston of an opposed pair of pistons is connected and by which the pistons are reciprocatable in a respective one of axially inline cylinders. The mechanism also includes a crosshead having opposite ends on each of which a respective piston is mounted, and a coupling between the crosshead and the crankpin by which the pistons are caused to oscillate circumferentially as the pistons are driven to reciprocate.
Claims20
An internal combustion engine having an engine mechanism including a crankshaft having a crankpin to which each piston of an opposed pair of pistons is connected and by which the pistons are reciprocatable in a respective one of axially inline cylinders, a crosshead having opposite ends on each of which a respective one of the pistons is mounted, and a coupling between the crosshead and the crankpin by which the pistons are caused to oscillate circumferentially as the pistons are driven to reciprocate.
The engine of claim 20, wherein compressor cylinder during an induction stroke has its inlet port is open to atmospheric air and its outlet port, and during a compression stroke its inlet port is closed and its outlet port is open under the pressure of compressed air, with the engine including a duct by which compressed air is able to be transferred to the inlet port of the power cylinder, with the duct having a volume enabling it to act as an accumulator of compressed air after the inlet port of the power cylinder closes.
