What is the latest technology being used in Diesel Engines?

  1. Direct Fuel Injection

  2. MPFI

  3. CRDi

  4. DTSi
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

CRDi (Common Rail Direct Injection) is indeed one of the latest technologies used in modern diesel engines. It uses a high-pressure common rail fuel system with precise electronic control, offering better fuel efficiency, lower emissions, and improved performance compared to older injection systems like direct injection or mechanical pumps.

What is the full form of CRDi?

  1. Central Rod Direct Ignition

  2. Central Rail Diesel Ignition

  3. Common Rail Diesel Injection

  4. Common Rail Direct Injection
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

CRDi stands for Common Rail Direct Injection. This technology uses a single high-pressure common rail that supplies fuel to all injectors, with electronically controlled injection timing and quantity for optimal combustion. The other options are incorrect: Central Rod/Rail variations don't exist as industry terms.

C Correct answer
Explanation

MPFI stands for Multi Point Fuel Injection (also called Multi-Point Fuel Injection). This gasoline engine technology injects fuel into each cylinder's intake port individually, providing better fuel atomization and efficiency compared to carburetors or single-point injection. Option A 'Many Point' is incorrect terminology.
