Consider the following statements for a multijet carburettor:1. Accele...
Statement 1: The acceleration jet is located just behind the throttle valve.
This statement is correct. The acceleration jet in a multijet carburetor is positioned just behind the throttle valve. Its purpose is to provide an extra fuel supply during rapid acceleration or high engine load conditions. By adding extra fuel, the acceleration jet helps to prevent a lean fuel mixture, which could cause hesitation or bogging down of the engine.
Statement 2: The main jet alone supplies petrol at the normal range of engine speed.
This statement is correct. The main jet is responsible for supplying the majority of fuel to the engine under normal operating conditions. It controls the fuel flow rate based on the engine's speed and load. The size of the main jet determines the air-fuel mixture ratio, with larger jets supplying more fuel and richer mixtures, and smaller jets supplying less fuel and leaner mixtures.
Statement 3: It has higher volumetric efficiency.
This statement is correct. Multijet carburetors are designed to improve the volumetric efficiency of the engine. Volumetric efficiency refers to the ability of the engine to effectively intake and exhaust air. By providing multiple jets and precise fuel delivery, a multijet carburetor can optimize the air-fuel mixture for better combustion and improved engine performance. This leads to higher volumetric efficiency, which translates to increased power output and fuel efficiency.
Statement 4: It has a robust design.
This statement is correct. Multijet carburetors are typically designed to be robust and durable. They are built to withstand the harsh conditions of the engine environment, including high temperatures, vibrations, and fuel impurities. The materials used in their construction are often chosen for their strength and resistance to corrosion. Additionally, the design of the multijet carburetor ensures that the fuel delivery system is reliable and efficient, contributing to its overall robustness.
Therefore, all the statements (1, 2, 3, and 4) are correct.
