The Volkswagen D24 engine is a 2.4-litre inline-six-cylinder (R6/I6), naturally aspirated diesel engine, formerly manufactured by Volkswagen Group from 1978 to 1995.

Subsequent forced induction variants of this engine were also available as the Volkswagen D24T engine with a turbocharger, and a turbo intercooled version, the Volkswagen D24TIC engine. These turbocharged variants resulted in higher power and torque outputs.

All variants (naturally aspirated and forced induction) displace 2,383 cubic centimetres (145.4 cu in) from a cylinder bore of 76.48 millimetres (3.01 in), and a piston stroke of 86.4 millimetres (3.40 in). Its inline six cylinder block is constructed from grey cast iron, and has seven main bearings to support the die-forged steel crossplane crankshaft. The cast aluminium alloy cylinder head contains two valves per cylinder each with two concentric valve springs, and shim-adjustable bucket tappets. The valves are opened via a timing belt-driven single overhead camshaft (SOHC), and the combustion chamber compression ratio is 23.5:1.
