5-Stroke Engines - What are these things?
What is a 5 stroke engine? They tend to consist of only three cylinders rather than the more traditional 4 stroke, 4 cylinder engines that many people are using today. There are two small small high-pressure cylinders and one larger low-pressure cylinder. This video has some good information and animations. Why aren't they using them in vehicles right now? PROS A secondary cylinder provides an additional expansion process enabling extra work to be extracted, which results in better thermodynamic efficiency (which means less thermal energy is wasted, hence the engine efficiency must increase) 5 stroke engines tend to be quite small as the firing (smaller) cylinders can be very highly rated The engine uses 100% conventional technology and so requires no new manufacturing techniques as such Intended to increase engine efficiency Intended to reduce emissions and fuel consumption A few reasons as far as I can tell: CONS Increased manufacturing costs due to the fact that it is not widely ado

I've found myself in the fortunate circumstances recently to be able to justify an extra driveway slot filler. Filling this final driveway slot would be a hindrance, in that it would make it harder to park, harder to load a 3 year old into the back of whichever car we wanted to use, make washing any of the cars very difficult without relocating something to the street temporarily... but it would fit a much needed requirement.I've never owned a car with more than four cylinders, or with more than 2.0 litres of capacity.I've been fantasising about what vehicle could help me fix this for years, a

Growing up in a small Scottish village in the 1980s, anything remotely exotic was a rare sight. Supercars lived in magazines, not on our roads.Then a new lad joined the school. His family moved into a very flash bespoke house on the edge of the village and, more importantly, his dad was a proper petrolhead. For the first time in my life I saw a Porsche in the flesh. I was about eight years old, and there it was: a Guards Red Porsche 944 sitting on the driveway.To an eight-year-old boy, it may as well have been a Ferrari F40.I stood staring at the thing in complete awe and made myself a promise
