intake

The primary function of the intake preheater is to elevate the temperature of the intake air by heating the air within the intake manifold, thereby enhancing both the cold start performance and combustion efficiency of the engine. There are several common types of intake preheaters: 1. Flame Jet Preheater: This type generates a high-temperature flame by burning fuel, directly heating the air in the intake manifold. During operation, an electric heating element energizes the valve body, causing the fuel to vaporize and ignite, producing a flame that sprays into the intake manifold. 2. Electric Heating Wire Preheater: This type utilizes resistance wire to heat the air. Upon energization, the electric heating wire rapidly heats up and transfers thermal energy to the air within the intake manifold. 3. Burner and Heat Exchanger Combination: Intake System Of The Automotive Engine burns fuel through a burner to produce high-temperature exhaust gases, which then transfer their heat to the incoming cold air via a heat exchanger, resulting in heated air entering the intake manifold. The intake preheater is primarily utilized in the following scenarios: 1. Low-Temperature Start: In cold environments, where the cylinder temperature is significantly lower during engine startup, the intake preheater can substantially increase the intake air temperature, ensuring reliable engine start-up. 2. Improved Combustion Efficiency: Preheated air facilitates better mixing of fuel and air, thereby improving combustion efficiency and reducing exhaust emissions. 3. Reduced Engine Wear: By mitigating excessive wear during cold starts, the Intake Preheater For Car helps extend the engine's lifespan.
