Analysis of the Audi DKW Engine?

[VonLeo]

Audi DKW engine is a four-cylinder four-stroke engine. The four-stroke engine belongs to the reciprocating piston internal combustion engine. DKW is a sedan produced by the German Audi company, popular in the 1930s and 1940s. Additional information about the Audi DKW engine is as follows: 1. Intake variable valve timing technology: The engine adopts intake variable valve timing technology, which can effectively improve intake and exhaust efficiency. This is mainly achieved through the vane-type hydraulic adjuster located on the intake camshaft to realize variable valve timing. The vane-type adjuster consists of an outer shell, an internal vane rotor, and a locking pin located inside the vane rotor. The outer shell is fixed to the external timing gear and driven by the crankshaft. The internal vane is directly fixed to the intake valve camshaft and rotates with it. 2. Working principle: It mainly controls the hydraulic oil in the corresponding pipeline through the camshaft adjustment valve to drive the vane in the adjuster, thereby rotating the camshaft to advance or delay the opening and closing of the valve. The adjustable range reaches 60° of crankshaft angle.
