Finally Daihatsu had made small ULEV (Ultra Low Emission Vehicle), which has become the top most selling Cars in indonesia.
Below are nowadays Daihatsu Automobile Engine Type, this LightWeight Engine, even small capacity but have enough big torque & power, but also smooth friction & economically fuel consumption.
they are applied in small-mini MPV cars like Perodua (in Malaysia),
Daihatsu Xenia, YR-V (Indonesia),
Toyota Avanza 1.5 & Rush (Indonesia) using 3Sz-VE , 1500 cc, DVVT, engine, same type but more bigger cylinder size
They are using all Daihatsu Engine it means that Daihatsu who make the engine not Toyota.. many people in here (indonesia) still didn’t realize this fact , they assume that Toyota brand is more better than Daihatsu.. indeed Toyota’s prize is more expensive 
with less features.
However i found that Avanza also has many advantages like :
+. has a bigger wheel & tire size than Xenia
-. Prices are higher / more expensive than Xenia
+. Brand Image are more better than Xenia
-. Default Bonus Features from it’s dealer are lesser than Xenia
+. Re-Sale Value are more better than Xenia
ENGINE VARIATIONS
K3-VET
1,298-cc, water-cooled, 4-cylinder, 4-cycle, 16-valve, DOHC, DVVT, turbocharged petrol engine
Adding a turbocharger with intercooler to Daihatsu’s powerful 1,300-cc K3-VE engine helped to achieve the highest output and torque of any engine in this displacement class. The turbocharger kicks in from low rpms. The DVVT (Dynamic Variable Valve Timing) system continuously adjusts the valve timing according to driving conditions. These technologies team up to give the K3-VET engine thrilling power at high rpms and hard-working torque at low and mid rpms. The result is a satisfying drive and an easy-to-handle engine at all speeds.
95 kW/6400 rpm
170 Nm/2800 rpm (YRV Turbo)
K3-VE
INDONESIAN MARKET
1,298-cc, water-cooled, 4-cylinder, 4-cycle, 16-valve, DOHC, DVVT petrol engine
This new-generation 1,300-cc engine is the fruit of Daihatsu’s efforts to develop ultra-lightweight engines that offer ultra-low fuel consumption and ultra-low emissions. The DVVT (Dynamic Variable Valve Timing) system here called VVT-i (Variable Valve Timing Inteligence), which continuously adjusts the valve timing according to driving conditions, helps the K3-VE achieve outstanding intake efficiency and exhaust performance. The result is an engine that combines high output and torque with exceptionally low fuel consumption and exhaust emissions.
75 kW/7000 rpm
120 Nm/4400 rpm (Sirion)
EJ-VE
989-cc, water-cooled, 3-cylinder, 4-cycle, 12-valve, DOHC, DVVT petrol engine
Daihatsu fit the DVVT system to a 1,000-cc 3-cylinder engine distinguished by high torque, low fuel consumption and low emissions. The result is the EJ-VE ﾑ a spirited engine offering even higher torque in the most commonly used rpm range plus lower fuel consumption and cleaner exhaust gas.
43 kW/6000 rpm
91.0 Nm/4000 rpm (Cuore)
EJ-DE
NON-DVVT
989-cc, water-cooled, 3-cylinder, 4-cycle, 12-valve, DOHC petrol engine
This efficient 1,000-cc 3-cylinder powerplant delivers generous torque in the most commonly used rpm range while keeping fuel consumption low. It offers an excellent environmental performance in terms of low CO and HC emissions and low-noise operation.
40.5 kW/5200 rpm
88.3 Nm/3600 rpm (YRV)
ENGINE TECHNOLOGY

| Intelligent Catalyst | |||
 Daihatsu has developed the world’s first “intelligent catalyst” with a precious metal (palladium) that self-regenerates by utilising the natural oxidation-reduction fluctuation in exhaust gas. This regenerating effect helps the catalyst maintain its initial performance for purifying the exhaust gas. |

|||
| DVVT (Dynamic Variable Valve Timing) | |||
| A computer optimises the valve timing according to such conditions as engine rpms and how far the accelerator pedal is depressed. | |||
| Daihatsu Original Catalyst | |||
 Daihatsu’s original technology led to development of this compact, high-performance, long-lasting catalyst for purifying exhaust gas. It replaces previous complicated, expensive systems that incorporate three separate catalyst converters. Called a “manifold converter” (it’s placed close to the engine), the new catalyst has just one catalytic converter yet achieves Japan’s ULEV (Ultra-Low Emission Vehicle) standards |
|||
| Two O2-Sensor System | |||
 This system places one O2 sensor upstream and one downstream from the Daihatsu Original Catalyst. The sensors detect oxygen levels in the exhaust gas and adjust the air/fuel ratio accordingly to maintain superior CO, HC, and NOx purification. |
