Baby Hitler posted:Plus having decades upon decades of nozzle/flow/pressure/atomization development in diesels maximizing power and efficiency using the same technology. Standard ~3bar pintle tip fuel injectors haven't really changed since their first use in the 60s with D-Jetronic. It should be noted that direct injection on diesel engines actually operates at a far higher pressure than direct injection in gasoline engines, our transit bus engines (cummins ISL) maintain their common rail systems in excess of 1500 bar, or about 22,000 PSI, minimum. This is a big part of the reason advanced diesel engines have continued to offer comical increases in performance, even with the clusterfuck of an exhaust system that's required to keep them clean. See: Ford powerstroke engines pushing 800 lb-ft of torque in the F-250, Caterpillar's C15 offering in excess of 2000 lb-ft of torque. I cannot comment on any reason why you could not do a similar common-rail system in a gasoline engine, that's well outside my qualifications.
