The engine utilizes high -
speed combustion technology and a variable control system for greater thermal efficiency output, which reduces energy losses associated with exhaust and cooling systems and the movement of mechanical parts, among other factors.
Not exact matches
No other petrol engine features direct injection at a pressure of 200 bar, spray - guided
combustion and piezo injectors, all in conjunction with map - controlled cylinder shut - off, an all - aluminium crankcase with «spectacle» honing, four - valve
technology with continuous camshaft adjustment, a high compression ratio of 12.6: 1, a start / stop system and generator management — while revving to a maximum
speed of over 7000 rpm.
MultiAir
technology helps maintain optimal
combustion at any
speed under any driving condition.
Advanced turbo
technology enables the Alfa Romeo 4C Spider to maximize torque at low engine
speeds and deliver more response to driver input by increasing
combustion efficiency and turbine
speed, all while eliminating turbo lag.
Advanced scavenging
technology enables the Alfa Romeo 4C to maximize torque at low engine
speeds and deliver more response to driver input by increasing
combustion efficiency and turbine
speed, all while eliminating turbo lag.
* The application of continuously variable valve timing
technology (MIVEC) to both intake and exhaust camshafts realizes valve timing optimally matched to engine
speed and load to stabilize
combustion characteristics and allow the engine to develop more power over the full rev range.
Advanced
technologies, including high -
speed combustion, multi-hole direct fuel injectors, a continuously variable capacity oil pump, a variable cooling system and VVT - iE intelligent variable valve - timing on the intake side give the engine maximum thermal efficiency of around 40 percent — an exceptional number for a passenger vehicle engine.
Using optimized BMW eDrive
technology, and with hybrid - specific all - wheel drive,
combustion engine driving the rear wheels and the electric motor driving the front wheels, the BMW i8 Coupe achieves 369 hp (12 hp more than its predecessor), a peak torque of 184 lb - ft, and accelerates from 0 - 60 mph in just 4.2 seconds (preliminary) with a top
speed of 155 mph.
MultiAir
technology delivers optimized
combustion at any
speed under all driving conditions by allowing direct and dynamic control of air intake and
combustion.
This is in part due to efficiency improvements, which will be led by advances in individual end - uses, such as lighting, variable
speed motors, and more efficient internal
combustion engine vehicles, as well as a shift from non-electric to more - efficient electric
technologies, the report says.
