This motorized inline-6 diesel truck engine model is built to replicate the scale and mechanics of a heavy-duty truck engine. Constructed from 3,236 pieces, it features six pistons moving in sequence, a working crankshaft, and a full inline-six layout that can be driven by hand or powered by the included electric motor. Detailed components such as twin turbochargers, exhaust manifolds, and cooling systems are integrated into the build, allowing you to clearly see how a diesel engine operates. Designed as a large, challenging build, it doubles as a realistic display model that demonstrates industrial engine mechanics in motion.
