Charge strautification increases part-load efficiency by 10-15%. Automotive diesel without supercharging has 50% smaller specific output and o 15% higher efficiency that engine strautified charge.</p>petrol engine with strautified chargeefficiencyautomotive dieselбензиновый двигатель с расслоением зарядомэкономичностьавтомо-бильный дизель[The internal combustion engines. 3 vol.
