Had a Honda in 1985 with CVCC engine that did the same function. Was rock solid.
Nothing screams reliable like an Italian car testing new technology.
"Maserati uses a very unique combustion process, instead of a basic single chamber for each combustion, Maserati just makes the entire engine Combust"
Tune in for next week's show, when we discuss piston head erosion in Maserati's MC20 engines.
Similar to the old International 6.9 and 7.3 IDI diesel engines. They were called IDI for Indirect Diesel Injection and had a Pre-combustion chamber.
You know there are serious car people here when you see Honda's CVCC mentioned.
Over a century later and we're back to Pre-combustion chambers like the old diesels of yester-year... So innovative....
They should call it CVCC, or Compound Vortex Controlled Combustion
We had that in the 1980 GAZ-3102 "Volga", japanese had that technology in the 1970's, and I believe that technology is even older
This adds potential for advancing ignition timing a lot more, sharper throttle response, and an engine that loves it's power band. All in all making for a really neat experience. I think koenigsegg should take notes from this method of initiating combustion. They've already got the "lights speed transmission". I feel that these technologies would make a great combination.
Yes, more power is always good.
The 1978 Honda Civic CVCC had done this. It had a precombustion chamber in its little 1200 cc 4 cylinder engine. I remember we would get over 50 mpg and with the car fully loaded. It was amazing. I remember one trip from Bakersfield to Los Angeles, we took a large dresser tied on the roof to a relative. We filled up before leaving and after the trip, we filled it again and checked the mileage then divided by the gallons we put in after, it came out to 52 mph. There were 5 people in that little car with a dresser tied to the roof!
So....basically 1980 Honda Civic CVCC cylinder head technology. The famous 3 barrel carburetor with two idle mixture adjustments.
My grandfather was a diesel engine mechanic in the East Texas oil fields during and after WW 2. He worked on the Waukesha engines that use the Ricardo pre-combustion chamber which greatly improved efficiency and power.
This was part of the massive merc avantage on the 2014 f1 season. Along with the split turbo.
In a gasoline engine it might be ground breaking but navistar has been using this idea since the early 80’s in the 6.9 and 7.3 IDI (InDirect Injection) Diesel engines. There’s a pre chamber with a glow plug and an injector, the glow plug heats up before starting, fuel is injected into the warmed up pre chamber compression then ignites the fuel and the combustion propagates into the cylinder. This is also the main limiting factor in this engine, and the reason it was replaced with the Powerstroke direct injection engine.
Honda called their stratified-charge engine “CVCC” (Compound Vortex Controlled Combustion) — way back in 1975 …
Man, they've been doing this on big diesel engines for ages. My grandpa tells stories about messing with them in the '50s
I saw an article many years ago about how a guy hit more efficiency and power in a engine buy cutting flame propagation lines into the head and piston to promote the flame spread so more power is given by making the flame front speed up
