    摘要： An engine charge control system operates by initially reducing power from full load by retarding exhaust valve (20) closing timing to increase exhaust gas charge dilution up to the limit for efficient operation. Further load reductions are made by reducing charge mass without increased dilution via alternative steps such as throttling (in conjunction with intake check valves or using individual cylinder valves) or retarding intake valve (19) opening timing without throttling. Partial substitution of external charge dilution is also contemplated.

    摘要： The internal combustion engine includes a compressor for supercharging intake air, an EGR device for introducing EGR gas into an intake passage at a position on an upstream side relative to the compressor, and a collecting pocket that is provided at an outer circumference of a compressor inlet and that collects condensed water generated inside the intake passage on an upstream side relative to the compressor. The collecting pocket opens towards the upstream side of the compressor, and is formed in a circular ring shape that surrounds the outer circumference of the compressor inlet. The collecting pocket includes a partition wall that holds back a flow of condensed water that attempts to move in a downward gravitational direction inside an internal space of the collecting pocket.

    摘要： An internal combustion engine (10) comprises rotatable bodies (24) each received in a respective internal cavity (20). The engine includes at least one inlet port (40,42) for each internal cavity in fluid communication with the combustion chamber(s) (32) thereof at least during their intake phase and a beginning of their compression phase. The bodies (24) are angularly offset with the beginning of the compression phase of the combustion chamber(s) defined by each body being simultaneous with at least a beginning of the intake phase of the combustion chamber(s) (32) defined by a different one of the bodies (24). A respective conduit (62,64) provides a fluid communication between an inlet port (40) for each body (24) and an inlet port (42) for the different one of the bodies (24), with each conduit (62,64) being in fluid communication with a plenum (21) for receiving pressurized air.

    摘要： An engine for use in an air hybrid vehicle comprises at least one cylinder having a piston (20) defining a variable volume working chamber (10) and intake (12, 14) and exhaust (16) valves controlling the flow of air into and out of the working chamber. The cylinder is operable in any one of at least two modes, namely a first mode in which power is generated by burning fuel in the working chamber (10), and a second mode in which the cylinder acts to compress air drawn into the working chamber (10) and to store the compressed air in an air tank (36). The engine further comprises a non-return valve (32) in an intake port leading to an intake valve (12) of the cylinder so as to define an auxiliary chamber (30) in the intake port between the intake valve (12) and the non-return valve (32). A passage (24) connecting the auxiliary chamber (30) to the air tank (36) contains a valve (34) for controlling the flow of compressed air between the auxiliary chamber (30) and the air tank (36). In the invention, a stop (40) is provided which is operative to prevent full closure of the intake valve (12) when the engine is operating in the second mode, whereby the air compressed in the working chamber by the movement of the piston is admitted through the open intake valve (12) into the auxiliary chamber (30).
