432 Q20 LTC Engines

The SkyAktiv-X engine does not misfire at low loads, because it implements two fuel-injection events per cycle.

• True.
• False.

The SkyAktiv-X engine fires the spark at high loads only, when it operates as a SIE.

• True.
• False.

The SkyAktiv-X engine performs better than conventional supercharged SIEs because it has a higher compression ratio.

• True.
• False.

(Brain Builder) The SkyAktiv-X engine runs on 87-ON gasoline, but it will perform better when fueled with 95-ON gasoline at the same r.

• True.
• False.

RCCI (dual-fuel) cars mix gasoline and diesel in the fuel tank.

• True.
• False.

RCCI engines control the duration of combustion by controlling the reactivity of the fresh-charge.

• True.
• False.

RCCI engines implement fully premixed combustion.

• True.
• False.

Combustion in RCCI engines starts

• when GASOLINE is injected.
• when DIESEL is injected.
• when the spark plug fires.
• when the end gas autoignites.

The primary fuel in RCCI engines is always diesel.

• True.
• False.
