Tech/Engineering - Engineering (general) / combustion engines
English term or phrase: knock
Most Otto Cycle Engines are four-stroke engines. They use gasoline, propane or natural gas (methane) as fuels, the oxidizer being air. In order to avoid knock (uncontrolled combustion) they are run lean (more air than needed to burn the fuel). This leads to the formation of NOx and also may lead to incomplete combustion (CO formation). Both are greenhouse gases. Most modern cars have direct fuel injection to prevent the possibility of unburned hydrocarbons.

Knock... więc niby spalanie stukowe... ale coś tu nie działa. Przecież uboga mieszanka sprzyja spalaniu stukowemu. Czy może chodzić o przedwczesny zapłon?


W innej części mamy:

(In older internal combustion engines a carburetor would have sprayed a liquid fuel into the low-pressure air when it entered the engine, leaving the motor subject to pre-ignition knock. For this reason current internal combustion engines are run lean.)

spalanie stukowe/stuk
Explanation:
Zbyt uboga mieszanka paliwowo-powietrza (za dużo powietrza, za mało paliwa) również sprzyja spalaniu stukowemu, tak jak za duży kąt wyprzedzenia zapłonu (zapłon następuje dużo za wcześnie przed osiągnięciem górnego maksymalnego położenia tłoka).

Notes to answerer
Asker: No tak, wg słownika tak by było. Tylko ten brak logiki... Jakieś pomysły na pre-ignition knock?
