My understanding is that they pre-ignite a tiny amount of fuel in a special chamber, which forces the main fuel-air charge into the cylinder through targeted nozzles, making a very effective and targeted fuel air mixture, which can be leaner as the mix is so good.
- exDM69 10y agoThis new jet igniter you mention is a fairly new development (not all teams have it yet) and is no doubt beneficial but it's probably not a huge increase in the efficiency on top of the clever hybrid technology. But it does provide a fair bit of power, and I'm looking forward to seeing Honda race it tomorrow for the first time (Mercedes and Ferrari have it already, Honda bringing it to Canada this weekend, not sure about Renault). This might improve McLaren's lackluster performance and even up the racing a little.
- cromulent 10y agoIt is actually quite a huge increase in the ICE. Ferrari's been using it for a year. "Furthermore, this process allows ... peak indicated thermal efficiencies up to 45% - not to be confused with the reported > 48% thermal efficiency that Mercedes is achieving for its entire F1 power unit." http://www.f1technical.net/news/20316 http://www.f1technical.net/news/20316
- exDM69 10y agoThanks for the good link. TJI seems to give quite nice increase in efficiency, up from the already impressive 40% or so they had in 2014. I don't remember anyone struggling with fuel loads in a long time like they did early on with the new engines.
