WATER BOOST INJECTION IN COMBUSTION ENGINE (Bosch)

The main benefit of water injection lies in lowering combustion temperatures within the engine. Like in the current compact turbocharged motors that are pushing their limits, both in terms of performance and fuel efficiency. Sasa, adding water to the air/fuel mixture lifts those boundaries by actively lowering the temperature within the combustion chamber, allowing a […]

Kuhusu KNOCK SENSOR

KNOCK SENSOR iko kama microphone ya kusikiliza sauti tofauti na ile kawaida ya engine. Kwa mfano mafuta na upepo kuchomwa kabla wakati au sehemu tofauti ya ile iliopangwa…yaani nje ya cylinder (combustion chamber). So hii video inajaribu kukumbusha jinsi KNOCK SENSOR inafanya kazi pamoja na jinsi ya kuipima ikiwa na shida! Share on: WhatsApp

DPF (emulator)

DPF ni “Diesel Particulate Filter” Tofauti na za petrol kutumia moto (spark), engine za diesel kuchoma mafuta ni kwa compression so hazichomi mafuta vizuri so zinatoa moshi hatari (unburnt fuels). DPF inawekwa ili kuzuia moshi hatari usitoke kwenye exhaust pipe jinsi wanaelekeza kwenye hii video! Hii DPF inakua kwenye exhaust pipe DPF inasafisha upepo mbaya […]
