Product Information:
Looking for a hands-on mechanical engine model? Explore the classic 1115-style layout with a working oil pump, evaporative water cooling and adjustable mechanical ignition, offering engine enthusiasts an engaging way to study traditional single-cylinder mechanics.
.Classic 1115-Styled Engine Design:
Based on the mechanical design and styling of the classic 1115 agricultural diesel engine, this approximately 1/7 scale model features a horizontal single-cylinder layout, 16mm bore, 19mm stroke, and approximately 3.6cc displacement, powered by gasoline with spark ignition.
.Full-Metal Construction:
The engine body is cast brass, paired with a large stainless steel flywheel for a distinctive mechanical appearance. With an actual operating engine system rather than a static display, it brings hands-on mechanical interest to a desktop collection.
.Mechanical Oil Pump Lubrication:
An engine-driven piston oil pump mechanically supplies lubrication to key moving components without an electric oil pump. Metal piston rings further improve the pressure feel while providing an intuitive demonstration of small internal-combustion engine lubrication.
.Evaporative Water Cooling:
The hopper-style cooling system uses natural water evaporation to carry off operating heat without a circulating water pump. A built-in drain tap allows cooling water to be released after use without removing the tank or using additional tools.
.Adjustable Mechanical Ignition:
The single-wire mechanical touch ignition system supports fine adjustment of ignition timing, allowing enthusiasts to explore engine tuning and operating characteristics. Suitable for engine model collectors, mechanical engineering enthusiasts, and educational demonstrations of single-cylinder engines.

Description:
.The 1115 Mini Gasoline Engine is a detailed mechanical model based on the classic 1115 agricultural diesel engine design. This horizontal single-cylinder power unit was historically associated with small agricultural machinery, irrigation pumps, and walking tractors in Asia. The model features a cast brass body and stainless steel flywheel, with an external structure and mechanical layout that draw from the traditional 1115 design.
.Unlike a static display model, it features an engine-driven piston oil pump that delivers engine oil to key moving components, demonstrating the lubrication principle without relying on an electric pump.
.The cooling system uses hopper-style evaporative water cooling. Heat is carried off through natural evaporation, while the tank includes a tap-style drain outlet for convenient coolant drainage after operation.
.The ignition system uses a single-wire mechanical touch configuration and supports fine ignition-timing adjustment. The timing can be adjusted slightly forward or backward according to operating conditions, providing an opportunity to explore engine starting, throttle response, and running characteristics.
.The engine also features metal piston rings for improved pressure characteristics and heat transfer, bringing the operating feel closer to that of a traditional mechanical engine.
