混凝土自動(dòng)上料攪拌車(chē)是在建筑工地更常見(jiàn)的一種專(zhuān)用車(chē)輛,建筑工地上一般路況都不好,而攪拌車(chē)因?yàn)檫\(yùn)輸介質(zhì)是混凝土,重量又比較大,所以在發(fā)動(dòng)機(jī)的選擇上多選馬力大,動(dòng)力足的,在購(gòu)買(mǎi)車(chē)輛的時(shí)候,我們常常聽(tīng)說(shuō)中冷增壓發(fā)動(dòng)機(jī)、渦輪增壓發(fā)動(dòng)。
Automatic concrete loading mixer is a special vehicle more common in construction sites. Generally, the road conditions on construction sites are not good. Because the transportation medium of mixer is concrete and its weight is relatively large, it is more likely to choose engines with high horsepower and sufficient power. When buying vehicles, we often hear of Intercooled supercharged engine and turbocharged engine.
中冷增壓就是當(dāng)渦輪增壓器將新鮮空氣壓縮經(jīng)中段冷卻器冷卻,然后經(jīng)進(jìn)氣管、進(jìn)氣門(mén)流汽缸燃燒室。的中冷技術(shù)可使增壓溫度下降到50攝氏度以下,有助于減少?gòu)U氣的排放和提高燃油的經(jīng)濟(jì)性。
Intercooling supercharging is when the turbocharger compresses the fresh air, cools it through the middle cooler, and then flows to the cylinder combustion chamber through the air inlet pipe and inlet valve. The intercooling technology can reduce the supercharging temperature below 50 ℃, which helps to reduce exhaust emissions and improve fuel economy.
中冷增壓實(shí)際上是一種空氣壓縮機(jī),通過(guò)壓縮空氣來(lái)增加進(jìn)氣量,它是利用發(fā)動(dòng)機(jī)排出的廢氣慣性沖力來(lái)推動(dòng)渦輪室內(nèi)的渦輪,渦輪又帶動(dòng)同軸的葉輪,葉輪壓送空氣濾清器送來(lái)的空氣,使之增壓進(jìn)入氣缸。
Intercooling supercharging is actually an air compressor, which increases the air intake through compressed air. It uses the inertial impulse of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber. The turbine drives the coaxial impeller, which presses the air sent by the air filter to increase the pressure into the cylinder.
當(dāng)發(fā)動(dòng)機(jī)轉(zhuǎn)速增快,廢氣排出速度與渦輪轉(zhuǎn)速也同步增快,葉輪就壓縮更多的空氣進(jìn)入氣缸,空氣的壓力和密度變大可以燃燒更多的燃料,相應(yīng)增加燃料和調(diào)整一下發(fā)動(dòng)機(jī)的轉(zhuǎn)速,就可以增加發(fā)動(dòng)機(jī)的輸出功率。
When the engine speed increases, the exhaust gas discharge speed increases synchronously with the turbine speed, and the impeller compresses more air into the cylinder. The pressure and density of the air become larger, which can burn more fuel. By increasing the fuel and adjusting the engine speed, the output power of the engine can be increased.
