The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system.

SwRI to Launch Low-Speed Preignition Prevention Program (P3) Consortium

Green Car Congress

OCTOBER 7, 2010

Southwest Research Institute (SwRI) will launch a new consortium—the Preiginition Prevention Program (P 3 )—focusing on fuels and lubricants to discover ways to suppress low-speed preignition (LSPI), a condition that causes heavy engine knock and can seriously damage engine parts or cause complete engine failure.

The range extender weighs a little more than 60 kg, together with the generators and all related parts. UniValve is a mechanical system for the simultaneous and continuous adjustment of valve lift and opening event. In order to reap the advantages of very early closure, the opening event must therefore be as short as possible.

Power for the battery and VTES electric supercharger is not only supplied by the SpeedStart ISG but also the TIGERS exhaust driven turbo-generator. Small displacement engines offer excellent CO 2 and fuel economy benefits; they have lower parasitic losses and operate more efficiently under part load conditions.

Due to the lower exhaust enthalpy of lower temperature engines using PPCI, it is difficult to produce intake boost with acceptable boost system parasitis. A practical powertrain system with robust PPCI combustion is needed, including injection, valvetrain, boost, and exhaust subsystems. —Sellnau et al. kWh and FSN 0.1,

Turbocharging and downsizing can also yield fuel consumption reductions. Downsizing is an important strategy applicable in combination with technologies that increase engine torque, such as turbocharging or supercharging. Part of the gain from advanced-level CI diesel engines comes from downsizing.

Since the pistons cyclically expose or occlude the exhaust and intake ports, there is no valve train. Because the intake and exhaust ports are at the opposite ends of the cylinder, opposed-piston engines have efficient, uniflow scavenging. Scavenging continues until a 230° crank angle, at which time the exhaust ports close.
