4TNV84 Engine Overhaul Gasket Kit YM729903-92670

Engine introduction

The engine is a diesel engine designed and produced by Yanmar, a Japanese diesel engine manufacturer. The following is some basic introduction to the 4TNV84 engine:
1. Structure and displacement: The 4TNV84 engine adopts an in-line four-cylinder, four-stroke structure. The usual displacement is 1.6 liters (1642cc).
2. Fuel system: This engine uses a direct injection fuel system, which injects diesel directly into the cylinder through the injector. Direct injection technology improves combustion efficiency and power output while reducing fuel consumption and emissions.
3. Power and Torque: Specific power and torque outputs vary by vehicle model and trim. Generally speaking, the power of 4TNV84 engine is between 20 and 35 kW, and the torque is between 80 and 150 N·m.
4. Technical features: The 4TNV84 engine uses turbocharging and intercooler technology to provide higher power output and fuel economy. The turbocharger increases intake airflow pressure, improving low-speed torque and power response. The intercooler cools the intake air, increases the oxygen density of the intake air, and further improves combustion efficiency.
5. Application scope: 4TNV84 engine is mainly used in small construction machinery and agricultural equipment, such as mini excavators, small loaders, lawn trimmers, generator sets, etc. With its compact, lightweight and efficient features, it performs well in small work spaces and scenarios with low power requirements.
6. Maintenance and maintenance: For the maintenance and upkeep of the 4TNV84 engine, it is recommended to perform regular maintenance in accordance with the manufacturer's service manual and recommendations. This includes changing oil and filters, checking and adjusting belt tension, cleaning and maintaining the cooling system, and more.

Gasket Kit Care Introduction

Engine gasket kits typically consist of a variety of materials used to seal and protect various components of the engine. The following are common 4TNV84 spacer kit materials:
1. Metal composite gaskets: Metal composite gaskets are usually composed of metal sheets and high-temperature wear-resistant materials (such as steel, copper, aluminum, etc.). They are used for sealing between the cylinder head and cylinder block of the engine to ensure the tightness and pressure of the combustion chamber work properly.
2. EPDM rubber gasket: EPDM rubber gasket has excellent chemical resistance, heat resistance and aging resistance. They are often used in the engine cooling system, such as the sealing of water pumps, water inlets and water outlets, to ensure the sealing and normal circulation of the coolant.
3. Paper gaskets: Paper gaskets are usually made from high-strength cellulose paper or compressed paper. They are often used in the intake and exhaust systems of engines, such as the sealing of intake manifolds and exhaust manifolds, to ensure the normal flow of airflow and prevent gas leakage.
4. Oil seal: Oil seals are usually made of rubber or silicone and are used to seal the crankshaft, camshaft and other rotating parts of the engine to prevent lubricating oil from leaking and external impurities from entering the engine.
