丰田此次将这款发动机的 EGR 率从 21%提高到了 28%。
2.改变活塞表面形状
丰田把这款发动机活塞表面的浅坑直径减小了,这样活塞对缸
内气体的扰动效果就更加明显。但是气体过高的流动速度,会很难点火。 为了解决这个问题,丰田的研究团队又提高了火花塞的点火能量,从

expansion、exhaust )
Four stroke Spark Ignition Engine
Stroke 1: Fuel-air mixture introduced into cylinder through intake valve Stroke 2: Fuel-air mixture compressed Stroke 3: Combustion (roughly constant volume) occurs and product gases expand doing work Stroke 4: Product gases pushed out of the cylinder through the exhaust valve
第三单元内燃机基础

4. Exhaust stroke
The fourth stroke is the exhaust stroke.
The piston moves up again and forces the burned gases out of the cylinder. The piston travels up to the top of the cylinder pushing all the exhaust out before closing the exhaust valve in prearation for starting the four-stroke process over again.
3. Power stroke
The third stroke is the power stroke.
Near the end of the compression stroke, the spark plug fires. Igniting The comressed air-fuel mixture that Produces a powerful explosion.

附件1:外文资料翻译译文内燃机我们知道,无论是汽油发动机还是柴油发动机,它们都属于内燃机,都是燃烧燃料后通过推动气缸内活塞作往返运动来将燃料中的化学能量转换成为驱动车辆前进的机械能量,因此两者的工作原理大体是相同的。
作为日常使用的燃料本身,柴油的能量密度最高,比液化天然气高出近1倍,比汽油高出10%以上。
与汽油相比,柴油不易挥发,着火点较高,不易因偶然情况被点燃或发生爆炸。
由于两者挥发性和燃点的不同,导致使用这两种燃料的发动机有不同的点火方式。
汽油发动机的特点:体积小、重量轻、起动性好。
汽油发动机中,油气混合气进入气缸后,在压缩接近终了时由火花塞点燃。
因此,汽油发动机需要一套控制何时让火花塞工作的点火系统,此系统必须精确控制火花塞放电的时刻和火花能量的大小,才能保证汽油机的工作正常,汽油机的燃料供给系和点火系是汽油机上发生故障比例较高的部位。
此外,由于汽油的燃点较低,汽油机的压缩比就不能太高,以免油气自燃,因此其热效率和经济性较柴油机为差。
汽油机的优点在于其体积小、重量轻、价格便宜;起动性好,最大功率时的转速高;工作中振动及噪声小,因此,在载客汽车,特别是轿车中,汽油机得到了广泛的应用,特别是在我们国家目前生产的绝大多数轿车,都是采用汽油发动机作为自己的动力系统。
传统柴油发动机的特点:热效率和经济性较好。
柴油机采用压缩空气的办法提高空气温度,使空气温度超过柴油的自燃燃点,这时再喷入柴油、柴油喷雾和空气混合的同时自己点火燃烧。
因此,柴油发动机无需点火系。
同时,柴油机的供油系统也相对简单,因此柴油发动机的可靠性要比汽油发动机的好。
由于不受爆燃的限制以及柴油自燃的需要,柴油机压缩比很高。
热效率和经济性都要好于汽油机,同时在相同功率的情况下,柴油机的扭矩大,最大功率时的转速低,适合于载货汽车的使用。

ENGINE STARTING EQUIPMENT
1 . Starting of Engines
An internal-combustion engine will operate cfficiently only under conditions of normal mixture formation and normal ignition and combustion of the fuel. The following difficulties may be encoun-tered in starting the engine.
When the crankshaft rotates slowly and the velocity of the air or mixture being drawn in is reduced, the formation of the mixture (especially in diesels) appreciably deteriorates. This results in a pressure drop at the end of compression stroke due to leakage of mixture or air through locks and air gaps in the piston rings, insuf-ficiently lubricated during the initial starting period. The tempera-ture of the compressed mixture or air decreases due to the lower pressure, but mainly due to the more intensive removal of heat th
2. Starting Engines
Starting engines must fire easily and reliably in any conditions, develop sufficient power, be small in weight and size, simple in design, and inexpensive.
Fig. 41. Type II-10M starting engine:
1-flywheel, 2-crankshaft bearing, 3-crankshaft, 4-cylinder, 5-connecting rod, 6-piston pin, 7-piston, 8-glow plug, 9-carburettor, 10-drive to diesel
Type II-10m (Fig. 41) starting engine is mounted on II-35, II-36, II-38, II-54, II-70, CMII-7 and other diesels. This is a gasoline left-hand rotation, single-cylinder, two-stroke carburetor crankcase-sca venged engine. It develops 10 hp at 3,500 rpm.
Type II-46 starting engine is installed on type 6kIIM-50 and KIIM-100 diesels. This is a two-cylinder, four-stroke gasoline-fired engine with a left-hand rotation. It develops a power of 19 hp at 2,600 rpm.
Power Transmission System of Diesel Starting Engine. The power transmission system brings the running starting engine into smooth engagement with the idle diesel and automatically disconnects the starting engine from the main engine after the latter has been started. If necessary, the power transmission system can beused to increase the torque transmitted by the starting engine.
The power transmission system of starting engines incorporates the following mechanisms (Fig. 42): clutch 8, reduction gear 7, mechanism 10 for automatic engagement and disengagement of drive gear 6. This mechanism operate s as follows.
The drive gear is engaged, i.e., shifted along its axis to the right until it meshes with the flywheel rim, by displacing body 5 by means of gear arm 1. This compresses spring 9 and draws apart loaded arms 2 whose lugs catch the bosses of the bush screwed into the shaft. The teeth of the arms and spring 3 Keep the mechanism engaged.
The mechanism is disengaged automatically when the speed of the diesel crankshaft attains 300-350 rpm. The centrifugal forces produced by the arm teeth will overcome the tension of spring 3 and draw the arms spart, while spring 9, thus released, will bring by means of rod 4 the body of the engaging mesh with the toothing of the diesel flywheel.。
