The Speed Evolution Piezoelectric Injectors Surpass Electromagnetic Rivals

Moreover, because of the higher velocity, the piezo injector could cause a better fuel penetration in the combustion chamber and, hence, a better fuel-air ... By eliminating the hydraulic servo mechanism between the actuator and nozzle needle, very fast injector response times are possible. Direct-acting piezoelectric ... How Bosch Piezoelectric Diesel Injector Works Amazon Printed Books https://www.createspace.com/3786463 Amazon Kindle Edition ... Increased injection pressure. • Less emissions. • Multiple-nozzle injection. • Enhanced injection timing. • 5 times faster than conventional injectors. 7. One type of fuel injector that offers precise metering of fuel is the piezoelectric fuel injector. Piezoelectric fuel injectors employ piezoelectric actuators ... “Piezoelectric actuators are suited to miniaturisation, they produce no electromagnetic noise and they are highly efficient.” PZT thin films can ... The correct answer is A, piezo, which allows for precise fuel metering leading to better fuel economy and reduced emissions. Piezo injectors ... ... actuators and key working units, and then changing the control settings. 2. Methods 2.1. Test object The tests were carried out on the Siemens VDO ... Consequently, it features much lower current consumption than that of an electromagnetic buzzer. The current consumption (excluding that of the peripheral ... According to Bosch, which introduced piezo injectors to the industry, a piezo actuator acts up to five times faster than a standard injector solenoid and the ...
