What does it mean when an engine smokes?
Smoke often leaves car engines as a result of overheating. This can be caused by faulty wire casings, heated residues on the engine block and overheated liquids including oil, transmission fluid and brake fluid. There may also be a fault in your coolant system, or your engine may not have enough lubricant.

What are the features of the Mazda Skyactiv G?
Features of SKYACTIV-G. ・The world’s first gasoline engine for mass production vehicles to achieve a high compression ratio of 14.0:1. ・Significantly improved engine efficiency thanks to the high compression combustion, resulting in 15 percent increases in fuel efficiency and torque.
Is the Mazda 2.0 SKYACTIV-G engine fuel efficient?
In the result, the 2.0-litre SkyActiv-G engine is 10% lighter than its predecessor, more powerful and fuel efficient. The engines satisfy exhaust gas emissions standard Euro VI in Europe. 4.0 (4.2 US qt.) – without oil filter. Strangely enough, there are no serious problems.
What causes unstable combustion in Mazda Skyactiv-G?
Exhaust gas temperature can be increased by delaying the ignition timing, but too much retardation causes unstable combustion. For SKYACTIV-G, stable combustion was realized even when the ignition timing after engine-start is considerably delayed.
What kind of fuel pump does SKYACTIV-G have?
That means that SkyActiv-G engine has a direct injection system and high-presser fuel pump. The fuel pump is driven directly by exhaust camshaft. The updated fuel system with direct injection provides pressure up to 2900 Psi (200 bar) because of high compression ratio and more top presser in the combustion chamber.
