Like the 1KR-DE, bore and stroke are at 71 mm × 84 mm (2.80 in × 3.31 in), respectively and engine displacement remains at 1.0 L (998 cc) [7] [8] The 1KR-DE2 achieves Euro IV emission standard and it is very fuel efficient due to the ECO Mode, where the engine will exchange drop one cylinder for every two cycles [citation needed], effectively ...
The DW8 was phased out in 2007 as it does not pass Euro 4 emissions regulations (it is a Euro 3 engine [1]). The DW8 is matched to the BE manual 5-speed and has 127 N⋅m (94 lb⋅ft) of torque. [4] This is known as the 1WZ engine in Toyota vehicles. Specifications. Displacement: 1.9 L (1,868 cc) Valves: 8 valve, single overhead cam
The OM646 engine is sold under the 200 CDI and 220 CDI designation and features an electric fuel pump, exhaust gas recirculation, particulate filters, [1] and Euro 4 emission standard compliance (from 2003). [2] In 2006, the engine was updated under the EVO name and replaced the OM647 engine.
The 4JA1-CR / 4JA1 Blue Power is a Euro 4 variant of 4JA1-L. Unlike its predecessor which used conventional Direct Injection, it uses a High Pressure Common rail Direct Injection system and Diesel particulate filter, [40] thus achieving Euro 4 emission. Power rated at 78 PS (57 kW) at 3900 rpm and 176.5 N⋅m (18.00 kg⋅m) at 1800 rpm.
The lower output versions have only a single turbocharger. There are also 2 shorter stroke "square" variants of this engine with 1.8 litre displacement 109 PS (80 kW) (badged A/B180) and 136 PS (100 kW) (badged A/B200 and used only in smaller front wheel drive models like the A-Bclass).
Compression Ratio: 11.5:1; Indonesia Euro 4 Version: 10.5:1; Valve Mechanism: 16-valve DOHC, Chain Drive (with Dual VVT-i) Fuel Injection System: Multi-point fuel injection; Emission Regulation: Euro 4 (Complies with Euro 5 after optimizations introduced in July 2010) Engine Service Mass (incl. coolant & oil): 89.5 kg (197 lb) Idling speed: 700 rpm
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
The four-stroke engine is more efficient when running at full throttle, while the opposite is the case for the two-stroke engine. When a small car under heavy load runs at half speed, the engine automatically switches to the two-cycle mode, which is then more efficient. The research on this showed a 27% reduction in fuel consumption. [8] [9]
