汽车燃烧效率？ 汽车汽油燃烧原理？英文双语对照

汽车燃烧效率？

答：汽车汽油燃烧率是接近100%的， 但是燃烧以后都使用效率不高， 只有30%左右， 相关原因如下: 目前主流的量产汽油内燃机的直接燃油效率在30％上下，有少数采用增压技术的量产发动机可以达到40％左右。制约效率的瓶颈主要在做功是需要克服的摩擦力、燃油的充分性等等的技术物理问题，因素有很多，比如循环效率、机械效率、燃烧效率、气室效率、气密性效率及制造工艺技术等等。

汽车汽油燃烧原理？

1.汽车燃油系统将汽油从油箱中送到发动机的燃烧室中。

2.燃油在燃烧室中与空气混合，形成可燃混合气体。

3.然后，火花塞产生电火花，点燃混合气体，使其燃烧。

4.燃烧产生高温高压气体，推动汽缸活塞运动。

5.活塞运动通过连杆和曲轴传递动力，驱动车轮转动，从而推动汽车前进。

6.燃烧产生的废气通过排气管排出车外。

需要注意的是，汽车发动机燃烧时需要足够的氧气，因此发动机需要通过进气道将空气引入燃烧室。此外，燃油的供应和混合气的比例需要经过汽车燃油系统的精确控制，以保证发动机的正常运行。

汽车燃烧有毒吗？

有毒

它有强烈的焦味。如果在行驶过程中闻到燃烧非金属材料的特殊气味，通常是离合器摩擦片燃烧或过热造成的。这种气味还会夹杂着烧焦的味道，因为离合器片是用橡胶、石棉等材料制成的。如果离合器使用正常，换挡或起步没有明显困难，车尾有异味，需要检查后刹车系统是否过热。一些粗心的车主一边拉手刹一边强行驾驶，会锁住后刹车片，产生灼热的气味。

汽车燃烧油什么成分？

汽油的主要成份是C5～C12脂肪烃和环烷烃类。

汽油的英文名为Gasoline（美）/Petrol（英），外观为透明液体，可燃，馏程为30℃至220℃，主要成分为C5～C12脂肪烃和环烷烃类，以及一定量芳香烃，汽油具有较高的辛烷值（抗爆震燃烧性能），并按辛烷值的高低分为90号、93号、95号、97号等牌号。

扩展资料：

汽油使用注意：

为车辆选用汽油的首要标准是压缩比，压缩比就是发动机总容积与燃烧室容积之比。比如，压缩比在8.0～9.0的汽车就适用93号汽油。使用低于适用标号的汽油发动机就易产生爆燃，即燃料在发动机内提前燃烧，这将造成发动机功率降低，油耗增加，汽车加速、爬坡无力。

时间长了还会使发动机过热，活塞、轴承等变形损坏。通过降低汽油标号来节省开支其结果不但不省钱，反而会给车主造成不可挽回的损失。而另一方面，也不要崇拜、迷信高标号汽油，油价高不说，在行驶时也并不能为你省油。

轮胎宽度：轮胎的宽度越宽，也就是轮胎接地面积越大越费油。摩擦力大了需要克服的阻力也就随之增大，你的车子在行进中每时每刻都会为增加的这一点阻力，再多付出一点燃油。

汽车燃烧系统如何保养？

汽车燃油系统分为油箱、油路、喷油嘴，在系统中有汽油泵，汽油滤清器等零件，燃油通过油泵、燃油滤清器、喷油嘴进入燃烧室燃烧，产生源动力动力。

在燃油系统的管路中充斥着由于燃油氧化产生的胶质，由于大气的物理现象，下雨，洗车等不可避免的会使水分进入油箱、油路中。

过多的胶质会导致汽油滤清器过早损坏及喷油嘴堵塞，而水分的存在会是汽油泵过早磨损，是油路中的金属元件锈蚀。

汽车燃烧需要氧气吗？

在我们这个世界的规则下面,燃烧是一种化学反应,物质发生剧烈的氧化反应.当然这个燃烧根据物质的性质不一定是和氧气发生.但是目前汽车使用的燃油是要和氧气一起才能燃烧,所以如果汽车在无氧的环境下无法燃烧,无法正常运行的.

发生燃烧的条件中最重要的一点就是氧气，没有氧气无法燃烧，所以不论在什么情况下，燃烧都是需要氧气的。

燃烧是化学现象，需要氧气，可燃物。所以在月球上没有氧气汽油是不可以燃烧的

新能源汽车燃烧比例？

我国新能源汽车每行驶4.47亿公里发生一次燃烧事故（2018-2019国家监管平台统计数据）。

汽车燃烧技术有几种？

1、缸内直喷燃烧技术

FSI 是 Fuel Stratified Injection 的词头缩写，意为燃油分层喷射，是直喷式汽油发动机领域的一项创新的革命性技术。

FSI燃油直喷技术在同等排量下实现了发动机动力性和燃油经济性的完美结合，是当今汽车工业发动机技术中最为成熟、最先进的燃油直喷技术，并引领了汽油发动机的发展趋势。

2、多点电喷燃烧

多点电喷技术是在单点电喷技术上发展起来的，取代了几个气缸共用一个喷油器的设计方式。

在每个气缸对应的进气歧管内加装了喷油器，这样避免了单点喷射过程中混合气输送和分配受进气歧管结构的影响，往往单点电喷难以实现所有工况下都能保持理想的混合气分配；

并且多点喷射将喷射器设在进气门处，燃油在热的进气门上进一步蒸发与空气充分混合后立即通过进气门进入燃烧室，不受到进气歧管结构的影响，可以保证一致的混合气分配。

汽车燃烧系统的讲解？

汽车燃烧系统包括传统的化油器汽油燃烧系统、电子控制的汽油喷射式燃烧系统、汽油直喷式燃烧系统、传统的柴油系统、电子控制的柴油喷式燃烧系统等。燃烧系统的作用:电子控制的汽油喷射燃烧系统是在恒定的压力下，利用喷油器将一定数量的汽油直接喷入汽缸或进气管内的汽油机燃油供给装置。

Is car combustion oily what composition?

Petrolic is main component is adipose hydrocarbon of C5 ～ C12 and cycloalkanes hydrocarbon kind.

Petrolic English name is Gasoline (beautiful) / Petrol (flower) , the exterior is transparent liquid, can light, cheng of heat up in a steamer comes for 30 ℃ 220 ℃ , bases is adipose hydrocarbon of C5 ～ C12 and cycloalkanes hydrocarbon kind, and measure balmy hydrocarbon certainly, benzine has higher octane number (antiknock shake burning behavior) , the cent of on any account that presses octane number is 90, 93, the 95 date, 97 brands such as date.

Patulous data:

Benzine uses an attention:

Choose petrolic for car first standard is compression ratio, compression ratio is engine total volume and firebox cubage than. For instance, compression ratio is in 8 ～ the car of 9 is applicable 93 benzine. Use the gasoline engine under applicable grade to deflagrate with respect to easy generation, namely fuel burns ahead of schedule inside engine, this will cause engine power to reduce, oily cost raises, the car is quickened, climb slope faint.

Time grew to still can make engine overheat, piston, bearing be out of shape attaint. Will save expenditure through reducing benzine grade its result not only not be economical, can give a car instead advocate cause beyond recall loss. And on the other hand, also do not adore, have blind faith in high grade benzine, oil price does not say high, also can not be you to save oil when travel.

Tire width: The width of tire is wider, namely tire contact area jumps over excessive consumption of fuel and oil greatly more. Attrition muscularity the resistance that need overcomes also increases subsequently, your car is afoot can be increasing this resistance all the time, pay a bit fuel more again.

How does car combustion system maintain?

Cent of car fuel system is gasoline tank, oil path, atomizer, there is gasoline pump in the system, the spare parts such as benzine filter, fuel enters firebox combustion through oil pump, fuel filter, atomizer, produce source power power.

Overmuch colloid meeting brings about benzine filter premature attaint and atomizer jam, and the existence of moisture can be gasoline pump wears away prematurely, it is oil path medium metallic component is rustily.

Does car combustion need oxygen?

In us below the regulation of this world, combustion is a kind of chemical reaction, material produces severe oxidation reaction. Of course this burning ground corporeal property is not certainly happen with oxygen. But the fuel that at present the car uses is to want to just can burn together with oxygen, if the car is below the environment that does not have oxygen,cannot burn so, cannot move normally.

The most important in producing flaming condition is oxygen, cannot burn without oxygen, fall in what circumstance no matter so, combustion needs oxygen.

Combustion is chemical phenomenon, need oxygen, combustible. Doing not have aerobic benzine on the moon so is not OK flaming
