    The Smartstream G2.5 GDi is an inline 4-cylinder engine with both direct and multi-port injection and a 13.0:1 compression ratio; the engine makes 194 PS (191 hp; 143 kW) at 6,100 rpm and 25 kg⋅m (181 lb⋅ft; 245 N⋅m) of torque at 4,000 rpm in the Sonata, for the Azera and Cadenza the engine makes 198 PS (195 hp; 146 kW) at 6,100 rpm and ...

  4. Ignition timing - Wikipedia

    en.wikipedia.org/wiki/Ignition_timing

    Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.

    en.wikipedia.org/wiki/BMW_N43

    The BMW N43 is a naturally aspirated four-cylinder petrol engine which was sold from 2006 to 2013. It replaced both the BMW N46 and BMW N45 engines. [1] However the N43 was not sold in countries with high sulfur fuel, [2] therefore the N45/N46 engines remained in production alongside the N43.

    First, the new AMC 2.5 replaced the four-cylinder engines purchased from GM. Second, AMC continued to purchase the 2.8 L V6 from GM until the 4.0 L I6 was introduced in 1987. The AMC 2.5 L I4 and GM's V6 shared the same drivetrain components in Jeep vehicles, whereas stronger transmissions were needed for the new 4.0 L.

    General Motors’ next-generation dexos1 specification (Dexos 1 Gen 2), [7] released in 2015, included an engine test based on a GM 2.0-liter four-cylinder Ecotec that will test for LSPI. [8] The ILSAC GF-6 standard (released in 2020) also include a test for oil-related LSPI events in gasoline direct-injection engines based on a Ford 2.0 L four ...

  8. Wasted spark system - Wikipedia

    en.wikipedia.org/wiki/Wasted_spark_system

    Ignition system of a flat-twin Citroën 2CV. A wasted spark system is a type of ignition system used in some four-stroke cycle internal combustion engines.In a wasted spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke.

  9. Engine knocking - Wikipedia

    en.wikipedia.org/wiki/Engine_knocking

    In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.
