摘要： A method to control a four-stroke combustion engine, comprising at least one cylinder; a piston arranged in each cylinder; at least one inlet valve arranged in each cylinder which is connected with an inlet system; at least one first camshaft which controls each inlet valve; at least one exhaust valve arranged in each cylinder which is connected with an exhaust system; at least one second camshaft which controls each exhaust valve; and a crankshaft which controls each camshaft. At least one phase-shifting device is arranged between the crankshaft and the second camshaft, to phase-shift the second camshaft in relation to the crankshaft to a state, where the exhaust valve is controlled in such a way, that it is opened during the expansion stroke of the engine and closed during the exhaust stroke of the engine, to achieve engine braking through compression in the cylinders during the exhaust stroke.

摘要： A control apparatus for an internal combustion engine (10) is configured to open a waste gate valve (48) when switching from supercharged lean burn operation to stoichiometric burn operation when it is necessary to decrease an air amount (Gair); control an exhaust variable valve train (30) so that, during a response delay period (τ D ') accompanying the waste gate valve (48) being opened, a valve opening period (EX1) and a valve opening period (EX2) are set, the valve opening period (EX2) overlapping with a valve opening period (IN); control a fuel injection valve (20) so as to inject fuel of an amount necessary to realize the stoichiometric air-fuel ratio under a stoichiometric requested air amount (Gair_req) and control the valve opening period (operating angle) (EX2) of the exhaust valve (28) during the response delay period (τ D '), so that the air amount (Gair) comes at least close to as requested (Gair_req).

摘要： Disclosed is an engine control system which is designed to allow homogeneous-charge compression ignition combustion to be performed in an HCCI region (R) defined as an engine operating region including at least a partial-load range of an engine. In a low load zone (R1) of the HCCI region (R), a lift amount of an intake valve (11) is set to a first predetermined value, and an exhaust valve (12) is allowed to start being opened during an intake stroke at a given timing later than an opening timing of the intake valve (11). Further, in the medium load zone of the HCCI region, the lift amount of the intake valve (11) is gradually increased up to a second predetermined value greater than the first predetermined value, along with an increase in an engine load. The engine control system is capable of adequately controlling an amount of burned gas to be introduced into a cylinder, depending on the engine load to allow the HCCI combustion to be adequately performed in a wider engine load range.

摘要： An engine system and a method of controlling a combustion process in an internal combustion engine are disclosed. The combustion process is based on compression ignition of a stratified air-fuel mixture using a high octane fuel such as gasoline. Multiple fuel injections may be used in a given combustion cycle. Fuel injection timing, EGR, exhaust rebreathing, late intake valve closing, and intake boost are controlled to enable autoignition over essentially the entire speed and load operating range of the engine, while providing reduced emissions, low noise, and low fuel consumption.
