What's Howin Engine L4-172?
The L4-172 is a miniature inline four-cylinder four-stroke engine model newly released by the HOWIN team, which demonstrates a strong engine manufacturing spirit. It is based on early real car engines that are widely used and designed with perfect style and appearance, recreating the elegance of full-size cars in scale models. Delivers a sense of realism from inline four cylinders to camshafts and rocker arms, every effort has been made even the scale&appearance of the engine to maintain a high-level performance that can provide extraordinary power to RC cars/ship models.
.Mainly decorated in silver and black for a high-end atmosphere, the L4 engine with an overall compact structure represents a collision of retro classics and modern machinery.
.Adopts SOHC valve mechanism, alloy rocker arms, independent intake/exhaust design and increasingly accurate valve opening/closing.
.Built with adjustable valve and single carburetor for easy adjustment and more sensitive throttle response.
.The intake pipe and exhaust pipe printed by integrated metal stainless steel make the engine sounds deep and powerful like a racing car.
.The integrated & reinforced crankshaft with five points to fully support ensures that the crankshaft boasts sufficient strength and is not easy to deform under high-speed operation.
.Utilizes the external centrifugal water pump and the cooling mode of direct contact between the outer wall of wet cylinder liner and coolant for heat dissipation with water drainage to prolong the working time and span life.
.Features smooth idle running and a high speed up to 15000rpm like a little violent beast, due to the 480 brush motor and convenient electrical starting.
.All parts of the model are made of carefully selected material, among which the piston ring is made of nodular cast iron, and the cylinder block & crankcase of the cylinder head are processed by aluminum alloy CNC, as well as colored through anodic oxidation after sandblasting.
.To maintain the steady output of the inline four-cylinder engine, the rocker arms, camshaft and crankshaft are precision machined for minimal tolerances.
.With its true-to-life scale, reliable start and steady power, the high-performance engine will meet the expectations of many model aficionados, providing an impressive&authentic model for nostalgic enthusiasts and collectors.
