Europe puri koshish kar raha hai ki traditional combustion engines ko kisi bhi tarah phase out kiya jaye. Agar European commission ki chale na, toh decision toh kab ka ho chuka hota or electric cars puri tarah takeover kar leti. But final vote toh member state ko hi karna hai 10 December ko. jisse decide hoga ki next 10 years mein kya hone wala hai. Abhi chances mixed hai, kuch bhi ho sakta hai, although kuch countries already favor mein vote dene ko ready hai.
In recent years, Europe ne traditional combustion engines ko literally bilkul hi target kar liya hai. Is technology ko poora villain bana diya gaya hai, synthetic fuels ya "hot hydrogen" jaisi cheezon ko bhi koi proper chance nahi mill raha. EU commissioners kaafi time se different technologies par crack down kar rahe hai, especially diesel cars ko, so that unhe as soon as possible market se push out kiya ja sake. Plug-in hybrids par bhi pressure chal raha hai. Germany ne Europe ko ek proposal send kiya hai so that PHEVs ka future secure rahe, but ek or traget bacha hai: petrol cars.
Why Europe does not want gasoline engines either?
Europe apna decision vehicle inspection stations ki report par nahi, rather independent studies ke base par karti hai, jinhe woh baad mein manufacturers or industry ko criticize karne ke liye use karti hai. Ek German research centre ki analysis ne yeh bataya ki petrol cars ki emissions diesel cars se worse hoti hai. CO2 ke terms mein nahi, rather particulate matter or nitrogen oxides ke emissions zyada hote hai. Yeh basically gasoline direct injection technology ki wajah se hota hai, jo fuel consumption or CO2 ke liye toh kaafi efficient hoti hai, but baaki emissions mein itni acchi nahi hoti.
Manufacturers ne petrol engines mein iss technology ko pretty much standard bana diya hai, because yeh kaafi fuel saving deti hai, best cases mein approx. 20% tak, especially low or mid RPMs par. But aaj-kal naturally aspirated direct-injection petrol engines almost exist hi nahi karte. Unki jagh turbocharged engines popular ho gaye hai, jo turbocharger use karke wide RPM range mein better performance dete hai, torque curve ko flatter rakhte hai, or fuel consumption or emissions ko control mein rakhte hai.
Bas problem yeh hai ki jab fuel ko directly combustion chamber mein high pressure se inject kiya jata hai, toh particulate matter-simple words mein, soot zyada generate karte hai.
Europe ab particulate matter ki badi toxicity par focus kar raha hai. sunlight lagte hi yeh particles chemical reaction se or zyada pollutants ban jaate hai. Problem yeh hai ki manufacturers in reactions ko rok nahi sakte, or unke particulate filters bhi ab inhe neutralize nahi karn pa rahe.
Isi wajah se Europe direct-injection petrol engines par nazar rakh raha hai. Abhi clear nahi hai ki in cars ko future mein kaise scrap kiya jayega, but haan koi na koi solution definitely niklega, maybe aise anti-pollution systems laa kar jo manufacturers ko kaafi push kar dein.
Dual injection would end Europe's debate, but it is expensive for both the brands and you
Yeh sach hai ki manufacturers ko solution pata hai: ek dual-injection system lagna, jismein direct injection ke saath-saath ek parallel indirect injection system bhi hota hai. Dono injection types easily saath mein kaam kar sakte hai, jaise Toyota GT86 ya phir Audi ka ab discontinue ho chuka 2.5-liter five-cylinder engine iski example hai.
Indirect injection itne high pressure mein kaam nahi karta jitna direct injection, because yeh fuel ko intake manifold mein inject karta hai, combustion chamber ke under nahi. Isse air-fuel mixture zyada smooth ban jaata hai or particulate emissions bhi kam hoti hai.
In simple words, indirect injection ka use sirf stating or initial acceleration wale phase mein hota hai, jab emissions sabse zyada hote hai, means engine ke low or mid-range RPMs par. High RPMs par jab max power chahiye hoti hai, tab direct injection ka kaam aata hai.
Problem yeh hai ki dono systems kaafi expensive hote hai mass-production cars mein lagane ke liye, or yeh cost directly car ke selling price mein dikh jaati hai.
Aaj-kal manufacturers electrification, hybrid or EVs par focus kar rahe hai, toh woh is old technology par extra paisa spend karna hi nahi chahte.
