MotorAuthority: Opel Insignia to debut HCCI sparkless technology (http://www.motorauthority.com/cars/general-motors/opel-insignia-to-debut-hcci-sparkless-technology/)

It appears General Motors will be the first manufacturer to use HCCI technology in its vehicles, with new reports claiming the revolutionary technology will first appear in the recently revealed Opel Insignia... ...Insignia will become the first production car to be equipped with HCCI technology.

HCCI works by achieving combustion through compression of the air-fuel mix rather than using a spark plug. This is similar to how a diesel works, but now the technology is being applied to petrol engines and is already showing 15% improvements in fuel efficiency.

AutoSavant: GM to Debut HCCI Sparkless Technology on Opel Insignia (http://www.autosavant.net/2008/05/gm-to-debut-hcci-sparkless-technology.html)
by Chris Haak

According to Motor Authority, GM’s new Opel Insignia (which is its replacement for the Vectra, and will also become the next Saturn Aura in the US) will be the first GM vehicle to feature HCCI sparkless ignition technology. It is not clear if the next Saturn Aura will also feature the HCCI technology at its launch.

HCCI, which stands for homogenous charge compression ignition... ...will only work from idle speeds up to about 55 miles per hour; beyond 55 or under increased load/power situations, conventional spark ignition would be employed to power the vehicle.

HCCI is basically a combination of gasoline and diesel engine technology; diesel engines also combust their fuel via compression ignition and not a spark plug. However, HCCI has the advantage of using gasoline instead of diesel fuel, and also the ability to combine the best traits of both gasoline engines (higher-RPM power, smoother and quieter operation, cleaner emissions) and diesel engines (low-end torque, fuel economy).

HCCI has nothing to do with hydrogen. It stands for Homogeneous Charge Compression Ignition.

thanks for the correction, Nsap
guess I've been more out-of-it than I knew :blush:


Ndw, does this thread need moving?

No problem.

I would probably leave it? It's not alternative fuel, but it's main purpose is to save fuel (15% improvement supposedly).
