L4 Engine 4 Cylinder 4 Stroke Water-cooled Electric Nitro IC Engine Model

The L4-172 Engine is a newly released miniature inline four-cylinder four-stroke engine model by Team HOWIN ENGINE, embodying a robust engine manufacturing spirit. Inspired by early real car engines, it features a stylish and realistic design that mirrors the elegance of full-size cars. With detailed components like inline four cylinders, camshafts, and rocker arms, this model delivers high-level performance, providing extraordinary power to RC cars and ship models.

Features:

Classic & Creative Colors: Mainly decorated in silver and black for a high-end atmosphere, the HOWIN L4 engine with an overall compact structure represents a collision of retro classics and modern machinery.

Single Overhead Camshaft: Adopts SOHC valve mechanism, alloy rocker arms, independent intake/exhaust design, and increasingly accurate valve opening/closing.

Adjustable Valve & Single Carburetor: Built with an adjustable valve and single carburetor for easy adjustment and more sensitive throttle response.

Integrated Design: Intake and exhaust pipes printed by integrated metal stainless steel make the engine sounds deep and powerful like a racing car. The integrated and 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.

Long Lifespan: Utilizes the external centrifugal water pump and the cooling mode of direct contact between the outer wall of the wet cylinder liner and coolant for heat dissipation with water drainage to prolong the working time and lifespan.

Speed Up to 15000RPM: Features smooth idle running and a high speed up to 15000rpm due to the 480 brush motor and convenient electrical starting.

CNC TECH: 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 and 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.

What It Presents: 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 and authentic model for nostalgic enthusiasts and collectors.

Requirement for Fuel: 20-25% Nitro Finished Fuel Oil. The gasoline modification kit to upgrade to use the gasoline fuel will be released later and will be available for purchase.

Warm Tips: The fuel tank, fuel lines, water cooling kits (radiator and water tank), and batteries need to be prepared or purchased.

Age Recommendation: 14-year-old +
