Probably the most common cause of that is a head gasket with a leak between the two, which could be caused by high compression / detonation (there are several possible causes for that including incorrect ignition timing, low octane gasoline), an engine overheat, uneven head bolt torques and / or a defective head gasket.
It's effective in only a narrow window of loads and engine speeds, necessitating spark ignition at other times — and switching between spark and compression ignition has proved complicated and expensive.
2) If compression is good, verify the ignition timing.
Most of the time, the Skyactiv - X engine operates under compression ignition.
Further boosting efficiency, the 1.6 - litre T - GDI engine receives a new high - energy ignition coil, higher - tumble intake ports, a low - friction timing chain and marginally higher compression ratio (from 9.5:0 in the cee'd GT to 10.0:0 in the new Sportage).
No matter how much you mute that characteristic compression - ignition sound, or how much you reduce the time it takes for glow plugs to reach operating temps, or how much range per tank you can enjoy, when the fuel gauge gets low, you still have to wrap your hands around a messy, oily, stinky pump to fill the tank.
Advanced compression ignition combustion systems — Control the complex pressure - temperature - time history within the combustion chamber to enable and extend low temperature combustion operation.
Mazda utilizes a lightweight rotating assembly (crank, rods, pistons), high 13 to 1 compression ratio (for added horsepower), automatic ignition timing (to prevent detonation), individual tube exhaust headers (for better performance and mileage) and an enhanced 6 - speed automatic (that is geared for both get up and go and fuel economy).
Then in calendar 2019, Mazda is likely to install first in the Mazda3 SkyActive - X, its homogenous charge compression ignition (HCCI) engine: a gasoline engine that most of the time ignites the fuel - air mixture by compression, just as a diesel does, but without the emissions challenges.
In other words, because a spark plug is now being used at all times, the engine can switch seamlessly between combustion using compression ignition and combustion using spark ignition.
Euro 5b legislation included, for the first time, a PN emission limit of 6.0 × 1011 / km to the mass - based limits for compression ignition engines established in Euro 5a.
