Ford now have a direct injection 3 cylinder engine which only needs the injection to run at half the present frequency and that is the simple and less efficient form of '8 Stroke'. Renault have run 8 stroke tests with computer controlled valves but their cycle did not achieve the full benefits. Honda have 8 stroke patents including US Pat No 5,529,032 but even this just misses the main advantages of my full '8 Stroke' system and is not in production. The 4 stroke cycle today is identical to the Otto cycle of 1876. It is time for a new cycle.
All cycles have advantages and dis-advantages.
8 Stroke' is more fuel efficient, cost effective and practical than all known alternatives including Direct Injection Petrol, Diesel, Hybrids and fuel cells. Profitable licences can now be granted for the main car making countries under my '8 Stroke' patents already granted. Demand would grow quickly as '8 Stroke' will appeal to drivers interested in economy and the more enthusiastic drivers who will like the instant acceleration response, the technical novelty and the changes in exhaust note. Please note that I claim Intellectual Property Rights for the general concept, the '8 Stroke' cycle itself or the 'Blackburn Cycle' which was ruled to broad and general to be included in my patent claims and will continue to be claimed in countries where I have no patents and when patents expire. I urge you to run tests.
