Honda Hybrid i-VTEC System

Fuel efficiency and less pollution is all the rage these days with cars. Honda brings us their updated IMA (Integrated Motor Assist) system to the 2006 Civic Hybrid.

The Hybrid i-VTEC system provides three stages of valve timing which are the low-rpm, high-rpm and cylinder idle mode. The IMA system is an improved version over the previous version, with battery output increased by 30% while retaining the same size. The electric motor employs coils with high-density windings and high-performance magnets to attain that power. The battery is recharged using regenerative hydraulic braking.

Honda says the system will perform equivalent to a 1.8 litre pure gasoline engine. Impressive.

Modes of operation:

  1. Vehicle stationary – The engine is turned off and fuel consumption is zero.
  2. Startup and acceleration – The engine operates in low-speed valve timing mode with motor assist.
  3. Rapid acceleration – The engine operates in high-speed valve timing mode with motor assist.
  4. Low-speed cruising – The valves of all four of the engine’s cylinders can be closed and combustion halted, the electric motor alone can power the vehicle.
  5. Gentle acceleration and high-speed cruising – The engine operating in low-speed valve timing mode powers the vehicle.
  6. Deceleration – The valves of all four of the engine’s cylinders are closed and combustion halted. The motor recovers a significant portion of the energy normally lost during deceleration and stores it in the battery.

Engine Specifications:

  1. Motor Assist – water-cooled inline 4 cylinder, 1,339cc. Max output – 95hp at 6000rpm, 119Nm torque at 4500rpm.
  2. Electric Motor – AC synchronous drive ultra-thin DC brushless motor rated at 158 volts. Max output is 20hp at 2000rpm, 140Nm torque at 0-1160rpm.
  3. Combined output – 115hp at 6000rpm, 183Nm torque at 2500rpm.

BTW in case you didn’t know, our Royal Malaysia Police force has 2 previous generation Honda Civic Hybrids in their fleet. This is Honda’s attack on the Toyota Prius’s reign in the hybrid market.

    Paul, I've received an email from my friend regarding some rumours stating that the Toyota Prius will be brought into Malaysia soon and priced very competitively at the region of RM70k. Can you do a search and comment on this? Thanx

  • One of the reason Malaysia won't have any electric car soon'

    Quote from somebody

    *Fast and powerful cars runing on batteries are possible, to create the vroom, vroom sound also an easy option, the main problem is….. which combine all the brain of top scientist in the world with the most advanced technology today still can't solve one major deadly problem we are facing in Malaysia… which is "there is no engine number in the car, we can't allow it to register and run on the road"*

    can anyone believe in Malaysia car policy???

    Ha ha….

    Another reason no electric allow in is~!!!!

    vic, what's this about no engine no.??? I'm sure any hybrid car would have engine nos.

    Anyway, for sure it will be th RM70k suggested by philip… retail price in other countries without considering the taxes is at least RM60k++ so add in the crazy taxes for the government to earn more money… equates to all of us hybrid cars lovers to suffer!!!
