In the naturally-aspirated diesel engine the density of the induced air is almost equal to the local air density. From this point of view the maximum weight of fuel that can be burnt efficiently is determined, therefore, the maximum power as well. If the density of charge air can be increased, then the weight of the charge air can also be increased, with a proportional increase in power. The large turbocharged diesel engine are designed with gas pulsation turbocharger. When the exhaust valve opens, the exhaust gas pressure is higher than scavenging pressure and after the initial rise of the exhaust valves, the pressure falls below the scavenging pressure. Therefore, the high energy exhaust pulses into turbine can be utilized to achieve better and effective scavenging.
