Os tempos do motor seriam semelhantes ao do motor a diesel, com o uso de velas sendo dispensado e trocado pela inje\u00e7\u00e3o direta de combust\u00edvel, v\u00e1lvulas com tempo vari\u00e1vel, turbo e supercompressor.<\/p>\n<p><a href=\"https:\/\/balconistasa.com\/wp-content\/uploads\/2021\/08\/Motor.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" alignright wp-image-358\" src=\"https:\/\/balconistasa.com\/wp-content\/uploads\/2021\/08\/Motor.jpg\" alt=\"Motor\" width=\"420\" height=\"204\" \/><\/a>Seu funcionamento \u00e9 baseado na compress\u00e3o do ar que j\u00e1 entra aquecido na c\u00e2mara (e que aumenta mais ainda quando \u00e9 comprimido), seguido da inje\u00e7\u00e3o de gasolina direto no centro da c\u00e2mara de explos\u00e3o. Por\u00e9m, no uso com gasolina, como ela precisa de cinco vezes menos compress\u00e3o do ar que o diesel, ela proporciona um uso mais suave, o que garante uma melhor efici\u00eancia do motor, al\u00e9m de uma opera\u00e7\u00e3o mais silenciosa.<\/p>\n<p>Para contornar os altos n\u00edveis de mon\u00f3xido de carbono causados por esse tipo de motor, o uso de um segundo catalisador garante as baixas emiss\u00f5es de gases nocivos ao meio ambiente. Comparado com um motor a diesel, o aumento na efici\u00eancia seria de 10% a 15%, o que expande o tempo de uso e mant\u00e9m a autonomia dos motores a explos\u00e3o. Como se n\u00e3o bastasse, a tecnologia gera um n\u00edvel baix\u00edssimo de polui\u00e7\u00e3o, equivalente ao de ve\u00edculos h\u00edbridos.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Menos \u00e9 mais<\/p>\n","protected":false},"author":1,"featured_media":1769,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[68],"tags":[69,97],"class_list":["post-357","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-autopecas","tag-autopecas","tag-motor"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Motores sem velas?
