The KA24DE is very similar to the KA24E. The KA24E is SOHC with three valves per cylinder actuated by rocker arms, and the KA24DE is DOHC with 4 valves per cylinder and shim-over-bucket valve actuation. Design improvements of the dual cam engine include the use of a knock sensor, larger diameter girdled main bearings in the Japanese block ...
The "V" designation is applied only if the engine has variable valve lift. ... KA24E, KA24DE; 1989–2015 Nissan NA engine — 1.6/2.0 L — NA16, NA20 - replacement ...

Both are naturally aspirated engines and are often less-powerful than the CA18DET and SR20DET engines used with its Japanese ...
A cylinder head of a four valve Nissan VQ engine engine. A multi-valve or multivalve engine is one where each cylinder has more than two valves (an intake, and an exhaust).A multi-valve engine has better breathing, and with more smaller valves (having less mass in motion) may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
Most of the 240SXs were equipped with the 2.4-liter inline-four engine (KA24E from 1989 to 1990 and KA24DE from 1990 to 1998).

Valve timing diagram for a 4-stroke engine. With traditional fixed valve timing, an engine will have a period of "valve overlap" at the end of the exhaust stroke, when both the intake and exhaust valves are open. The intake valve is opened before the exhaust gases have completely left the cylinder, and their considerable velocity assists in ...
