Sometime in 2008 through 2021 some engines are designated as D4CB-L A II which was a low-power version that is rated only for 122 kW (163 hp; 165 PS) instead of the usual 127 kW (170 hp; 172 PS). 2011 models and beyond are also equipped with a standard particulate filter for emission compliance purposes.
The oil pressure idiot light lights when engine oil pressure drops below a predetermined level. The light normally appears when the vehicle ignition is turned on, but the engine is not running, as it detects no oil pressure due to the oil pump not operating (the oil pump is powered off the crankshaft, so only operates when the engine is running ...
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

A severe form of engine flooding occurs when excessive liquid fuel enters the combustion chamber. This reduces the dead volume of the combustion chamber and thus places a heavy load on the starter motor, such that it fails to turn the engine. Damage (due to excessive compression and even dilution of the lubricating oil with fuel) can also occur.
Hyundai Motor Company has produced the following families of automobile engines. Gasoline engines use a naming system based on Greek letters. Spark Ignition (Gasoline) Straight-3. Epsilon ε - 0.8 L; Kappa κ - 1.0 L; Straight-4. Epsilon ε - 1.0/1.1 L; Kappa κ - 1.2/1.25/1.4/1.6 L; Alpha α - 1.3/1.4/1.5/1.6 L; Gamma γ - 1.4/1.6 L; Sirius ...
However, when they wear, their effectiveness drops, which leaves oil on the cylinder walls during combustion. In some engines, burning a small amount of oil is normal and shouldn't necessarily cause any alarm, whereas heavy oil consumption is a sign that the engine might need an overhaul.
These engines were designed to have a total-loss lubrication system, with the motor oil held in a separate tank from the fuel in the vehicle, and not pre-mixed with it as with two-cycle engines, but mixed within the engine instead while running. Castor oil was often used because it lubricates well at the high temperatures found in air-cooled ...
In September 2015, Hyundai recalled about 470,000 model year 2011-2012 Sonatas equipped with 2-liter and 2.4-liter Theta II engines. At the time, Hyundai told NHTSA that manufacturing problems left metallic debris around the engine crankshaft, causing problems with oil flow.
