1. Musiyano pakati pesimba uye torque

Mumamiriro ezvinhu akajairika, silinda yeinjini yepeturu ipfupi. Chikonzero nei dhizaini iyi yakagamuchirwa ndeyekuwedzera kukurumidza kukurumidza kwejini, kuitira kuti iparadze simba rakawanda. Kusiyana neizvi, injini dzedhiziri dzinobhadhara zvakanyanya kune torque yemotokari, uye silinda sitiroko inoiswa kuti iite kureba, iyo inogona kuderedza kumhanya kwemotokari uye zviri nani kuwedzera torque. Nokudaro, ichi ndicho chikonzero nei motokari dzinorema-dzisiri mumugwagwa, maSUV, marori, nezvimwewo vose vanosarudza mafuta einjini yedhiziri semagetsi avo.

2. Upfumi hwemafuta

Iyo inonzi hupfumi hwemafuta, kuenzanisa kwakanyanya ndeye kuenzanisa kushanda kweinjini mbiri mukushandura simba rekupisa mumagetsi emagetsi. Nekudaro, nekuda kwekumwe mutsauko muinjini tekinoroji kubva kune vakasiyana vagadziri, kune mimwe misiyano mukupisa kwesimba rekushandura kushanda kweinjini. Parizvino, kushandurwa kwekupisa kweinjini dzemotokari kwagara kuri dambudziko. Kupisa kwemafuta einjini zhinji dzepeturu kunogona kungosvika makumi mana muzana. Chete kushandurwa kwekupisa kweinjini inogadzirwa nemhando dzakadai seNissan neMazda kunogona kudarika 40%. Kune rimwe divi, kumajini edhiziri, iyo shoma yekudziya yekushandura inoshanda iri pamusoro pe35%, uye zviri nyore kudarika 40%. Iko kune dzimwe injini dzine simba rekupisa rinogona kudarika 45%. Nokudaro, kushandisa huwandu hwakafanana hwehuni, injini yedhiziri inogona kushandura simba rinopisa kuti rive simba remagetsi, izvo zvinoreva kuti inonyanya kushandisa mafuta.

Mukuwedzera, iyo yakaderera kupisa kwemafuta einjini dzepeturu zvakare yakabatana zvakanyanya nekuumbwa kwepeturu. Kubva pamakemikari ekuona, peturu nedhiziri zvinoumbwa nemamorekuru madiki, uye kune yega yega hydrocarbon compound molecule, kune anenge 8-10 peturu mamorekuru. maatomu ecarbon, nepo mamorekuru edhiziri anogona kusvika 12-15 maatomu ecarbon. Iyo yakakwirira iyo carbon atomu yemukati, iyo yakakura simba rinowanikwa mushure mekutsva. Naizvozvo, kuti iwane simba rimwe chetero, injini yepeturu inoda kubaya mafuta akawanda kupfuura injini yedhiziri, uye kushandiswa kwemafuta kunongove kwakakwira.

 3. Kuvimbika kweinjini uye kuchengeteka

Hupenyu hwesevhisi hweinjini hwakabatana zvakanyanya nekumhanya kwekutenderera. Iyo yakakwirira yekukurumidza kushanda, iyo ipfupi hupenyu hwesevhisi. Semuyenzaniso, injini inoshandiswa mumotokari dzemujaho weF1 ine sipidhi idling ye3,000 rpm, uye avhareji yekumhanya kweinjini iri pamusoro pe15,000 rpm kana injini iri kushanda, saka zvinongotora mijaho mishoma kuti injini itumirwe kure. . Kudzokera kuchokwadi, injini dzedhiziri dzinobhadhara zvakanyanya kune yakaderera torque, saka kana simba rimwe chetero rasvika pakumhanya kwakafanana, kumhanya kweinjini yedhiziri kwakadzikira. Mukuwedzera, kunyange pakumhanya kwepamusoro, injini yedhiziri kazhinji haipfuure 4500 rpm, nepo injini yepeturu ine hupamhi hwepamusoro hunosvika 6500 rpm kuitira kuti iwedzere simba rakawanda rebhiza. Naizvozvo, injini dzedhiziri dzine yakaderera rpm dzinowanzovimbika.

Diesel haina kushanduka uye haisi nyore kubatidza patembiricha yakajairika. Naizvozvo, kana tsaona yeinjini yedhiziri ikaitika, mukana wemotokari inongobatidza moto zvakare mudiki. Kusiyana nemotokari yepeturu, kana tangi remafuta radonha, kamoto kadiki chete kanogona kuibatidza. Pakarepo inotungidza mota yese.
