Mafungiro asiriwo: “Mota ine injini yedhiziri inosvibisa zvakawanda kupfuura motokari ine injini yepeturu.
Mota dzedhiziri dzinoita zvikamu zvitatu muzvina zvezvikepe zveFrance. European rekodhi! Asi mumakore achangopfuura, maererano faindi dzezvakatipoteredza uye zvinonyadzisa zvakaita seDieselgate, injini dzedhiziri hadzisisina mukurumbira. Asi pane maonero akapararira nezve mafuta edhiziri: inosvibisa kupfuura peturu, pane zvinopesana, zvishoma ... Vrumli anodudzira aya ma clichés!
Chokwadi kana Nhema: "Mota ine injini yedhiziri inosvibisa kupfuura mota ine injini yepeturu"?
CHOKWADI, asi...
Diesel ine marudzi akasiyana ezvinosvibisa: zvimedu zvakanaka, ipapo nitrogen okisijeni (NOx) uye gasi rinodziya... Kana zviri zvimedu zvidiki, particulate filters (DPF) vava kuiswa painjini itsva yedhiziri. DPF inofanirwa, asi yeFrance mota ngarava ndeyekare uye ichine mota zhinji dzedhiziri dzisina mafirita.
Kune rimwe divi, injini yedhiziri inoburitsa magasi egreenhouse mashoma pane mota yepeturu. Diesel injini inopenya kumativi % ye10 CO2 zvishoma kupfuura injini yepeturu! Kune rimwe divi, mafuta edhiziri anonyatsoburitsa yakanyanya NOx kupfuura mota yepeturu. Nechikonzero ichi, mafuta edhiziri anoonekwa seasvibisa kupfuura peturu.
Kutaura zvazviri, kupisa kwemafuta edhiziri hakuna kufanana neiyo peturu. Nekuda kweizvi, uye kunyanya nekuda kwemweya wakawandisa unoreva izvi, mafuta edhiziri anogadzira mamwe ma nitrogen oxides kunyangwe paine fambiro mberi yesainzi mumakore apfuura.
Saka, mota yedhiziri inoburitsa kanenge kaviri NOx semota yepeturu. Nekudaro, nitrogen oxides inobatsira kune iyo greenhouse maitiro uye anenge 40 times more chepfu kupfuura carbon monoxide.
MuFrance, mota dzedhiziri dzinoita 83% yenitrogen oxide emissions uye 99% yehunyoro hunobva kumota dzese dzinotakura vanhu. Gore rega rega kutenderera pasirese, makumi ezviuru zvekufa zvinosanganisirwa neNOx uye yakanaka particulate nyaya, iyo inonyanya kukonzera iyo injini dzedhiziri. Ichi ndicho chikonzero icho mutemo uri kugadzirwa kuderedza kusvibiswa kwemotokari idzi.
