Engine – Static Description

The manual details the engines available, including those with 4 cylinders (TT75) and 3 cylinders (TT55), as well as the naturally aspirated 3-cylinder with a turbocharger (TT65). These engines are designed with cross-flow cylinder heads, with intake and exhaust manifolds positioned on opposing sides. The combustion process is specially engineered to occur within the specially designed cavity in the pistons.

Cylinder Head Assembly

The cylinder head features valves and springs, and the valve rocker arm shaft assembly is secured to the cylinder block via the cylinder head. Retaining bolts are arranged in a six-point pattern around each cylinder to guarantee even pressure across the cylinder head. The right-hand side houses the intake manifold and diesel injectors outside the rocker cover, while the left side accommodates the exhaust manifold.
