Control device and control method for internal combustion engine with supercharger

Номер: US20150013637A1
Автор: Masaharu Kassai
Принадлежит: Nissan Motor Co Ltd

An internal combustion engine ( 1 ) is provided with a supercharger ( 12 ) and a cylinder direct injection fuel injector ( 10 ). When the engine shifts in a low-speed supercharging region at a state where the wall temperature of a cylinder bore ( 3 ) is low, liquid fuel adheres to a wall surface of the cylinder bore ( 3 ) so that lubricating oil is diluted with the liquid fuel and released into a combustion chamber ( 4 ). As a result, there occurs abnormal combustion. In the present invention, the fuel injection amount is increased at the time when the engine shifts in a predetermined low-speed supercharging region. The lower the wall temperature of the cylinder bore, the larger the rate of increase of the fuel injection amount. This makes it possible to suppress the temperature of air-fuel mixture in the vicinity of compression top dead center and prevent the occurrence of abnormal combustion.

A supercharger intercooler includes three sequential Anti-Reversion Plenums (ARPs) separated by heat exchangers, in right and left air paths between the supercharger and intake ports. The intercooler resides above and beside the supercharger and has paths for each bank of a V8 engine. An air flow from the supercharger is up and into a first ARP, is split into right and left flows into right and left first heat exchangers, passes into second ARPs and turns down, flows though right and left second heat exchangers into third ARPs and then into the engine. Reversion pulses from the engine are reduced by each ARP, increasing air flow into the engine, and reducing pulsations in the air flow, thereby increasing power, improving fuel economy, throttle response, driveability, and reducing emissions. 1.

Автор: Daniel S. Pedersen, Guy R. Babbitt, Kristina Weyer-Geigel
Принадлежит: Onboard Dynamics Inc

Typically, an engine-compressor for compressing natural gas for use as a fuel has a single cooling circuit to cool both its combustion unit and compression unit. A single cooling circuit design is not ideal because the optimal temperature for the combustion unit is higher than the compression unit of the engine-compressor. The present invention provides a dual zone cooling system to cool the combustion unit separately from the compression unit.
