Kamui77 hat geschrieben:Bei Honda ist man leider noch einen Schritt zurück. Dort hat man zwei Downsizing-Motoren (1.5L + 1.0L) entwickelt die in den nächsten Civic kommen. Kein Atkinson/Miller-Zyklus, keine gekühlte Abgasrückführung und beim 1.5L nicht einmal V-TEC
So wie der Motor gebaut ist braucht er kein i-vtec er hat aber DOHC und dual VTC...
L15B7 US spec:
1.5L Turbo Engine Specs:
174 horsepower @ 5500 rpm
162 lb-ft @ 1800-5500 rpm
Single-scroll turbocharger
16.5 psi boost
31 city mpg, 42 highway mpg, 35 combined mpg
Direct injection
DOHC (dual overhead cam) driven by timing chain
Dual VTC (variable valve timing control)
Cylinder head with the built-in water-cooled exhaust manifold
Aluminum block and cylinder heads
Exhaust-port passages cast directly into cylinder head (eliminating separate exhaust manifold)
Drive-by-wire throttle
Cavity-shaped pistons and optimized skirt design minimize vibration and increase operating efficiency
Lightweight steel connecting rods are heat-forged in one piece for higher strength
New grinding process known as plateau honing further lowers friction level between pistons and cylinders
0W-20 oil
Regular (US-grade) unleaded 87 gasoline
Mechanical high-pressure fuel pump
Sodium-cooled exhaust valves
Differences from 2.0L engine:
Mono scroll turbo system with electric wastegate and intercooler allows for turbo boost to be built up with relatively small throttle openings and low rpm.
Compression ratio of 10.6:1.
Smaller M12 spark plugs
0-60:
C&D achieved 6.8 sec
Motor Trend achieved 7.2 sec w/ touring model
[Official spec not yet released]
1/4 mile:
C&D achieved 15.3 sec @ 94 MPH w/ touring model
Motor Trend achieved 15.5 sec @ 92.4 MPH w/ touring model
