There are many reasons for the increase of fuel consumption of self-propelled mixer. But the common and easy to be ignored is the inspection of tire pressure. Insufficient tire pressure will not only increase the driving resistance and fuel consumption, but also affect the service life of self-propelled mixer tire.

自走式攪拌車預(yù)防耗油的方法：自備胎壓測(cè)量器，經(jīng)常檢查自走式攪拌車輪胎氣壓。切記不要忘記備胎的檢查，以免急需更換備胎時(shí)，才發(fā)現(xiàn)備胎不能使用。氣溫高時(shí)胎壓會(huì)比平時(shí)高一些，冷天或陰涼處測(cè)量的胎壓比較準(zhǔn)確。輪胎每行駛1萬(wàn)km要互換位置，避免前后磨損程度相差太大。如果需要更換磨損嚴(yán)重的輪胎，好2個(gè)或4個(gè)一起更換，紋路相同的輪胎可以前后交叉更換。另外，折線花紋的輪胎有助于節(jié)省燃油。

Methods to prevent fuel consumption of self-propelled mixer: provide self-contained tire pressure gauge and check tire pressure of self-propelled mixer frequently. Remember not to forget the check of the spare tire, so as not to find that the spare tire can not be used when it is urgent to replace it. When the temperature is high, the tire pressure will be higher than usual. The tire pressure measured in cold weather or in the shade is more accurate. The position of the tires should be changed every 10000 km to avoid too much difference between the front and rear wear. If it is necessary to replace the severely worn tires, two or four of them should be replaced at the same time, and the tires with the same grain can be replaced alternately. In addition, the tire with broken line pattern helps to save fuel.

自走式攪拌車的電器系統(tǒng)由三部分組成：冷卻風(fēng)扇控制部分和后示廓燈部分。

The electric system of self-propelled mixer consists of three parts: cooling fan control part and rear position indicator part.

自走式攪拌車?yán)鋮s風(fēng)扇控制部分：冷卻風(fēng)扇的起停由溫度開(kāi)關(guān)自動(dòng)控制，溫度高于 6 5℃時(shí)風(fēng)扇啟動(dòng)，低于60℃時(shí)風(fēng)扇停止。溫度開(kāi)關(guān)位于冷卻器上，繼電器與保險(xiǎn)片在蓄電池旁電源繼電器盒內(nèi)。后示廓燈部分：后示廓燈用于夜間表示車后部輪廓大小，與后牌照燈同時(shí)點(diǎn)亮與熄滅。

Self propelled mixer cooling fan control part: the start and stop of the cooling fan is automatically controlled by the temperature switch. The fan starts when the temperature is higher than 65 ℃, and stops when the temperature is lower than 60 ℃. The temperature switch is located on the cooler, and the relay and fuse are in the power relay box beside the battery. Rear clearance lamp part: the rear clearance lamp is used to indicate the size of the rear contour of the vehicle at night, and is on and off at the same time as the rear license plate lamp.

自走式攪拌車主要電器元件包括：一個(gè)繼電器和繼電器底座、閃光蜂鳴器、推拉開(kāi)關(guān)、紐子開(kāi)關(guān)、片式保險(xiǎn)及接線座等。

The main electrical components of self-propelled mixer include: a relay and relay base, flashing buzzer, push-pull switch, button switch, chip fuse and wiring base, etc.
