The thermostat is equipped with a temperature-sensitive wax or liquid that expands and contracts in response to changes in temperature. When the engine starts and is cold, the thermostat remains closed, preventing coolant from circulating through the radiator. This allows the engine to reach its optimal temperature more quickly. Once the engine warms up to the predetermined temperature, the thermostat opens, letting coolant flow through the radiator to dissipate heat and keep the engine from overheating.

The advantages of 2-cycle engines are evident in terms of size, weight, and power delivery. They produce strong power outputs and can operate in any orientation, making them versatile for diverse applications. However, there are trade-offs. One significant drawback is fuel efficiency; 2-cycle engines tend to consume more fuel since they often do not use a dedicated lubrication system, leading to some unburned fuel being expelled as exhaust. This inefficiency is compounded by environmental concerns, as they tend to generate higher emissions compared to their 4-cycle counterparts.
