Honda's old Fit 1. Is the valve of 3DSI engine mechanical or hydraulic tappet?

Fit engine is equipped with the compact engine of Guangzhou Honda Fit 08 series car, which consists of 1.3 liter and 1.5 liter. They all adopt the design ideas of in-line four-cylinder, 16 valve, SOHC (single overhead camshaft) single overhead camshaft, liquid cooling and I-VTEC (intelligent variable valve timing and lift electronic control) intelligent variable valve timing and lift control system. By improving the medium circulation path of liquid cooling system, increasing the valve diameter, optimizing the piston shape, adopting high-strength connecting rod, aluminum rocker arm, DBW (drive-by-wire throttle system) electronic throttle system and the world's first piston pattern coating, the power and torque of the new engine have been greatly improved, and the fuel economy of the engine has also been further improved. The new engine adopts a tightly coupled two-stage TWC (three-way catalyst) three-way catalytic tail gas conversion control system, and the first-stage catalytic converter is directly connected with the exhaust side of the cylinder head, which makes the engine lightweight and compact, and improves the emission control performance of the engine at low temperature cold start. The new engine not only achieves a more reasonable combination of power output and fuel economy, but also makes the matching vehicles reach a higher level of environmental protection with ultra-low energy consumption and emissions. The output power of 1.3L is increased from 60kW to 73kW, and that of 1.5Li-VETC engine is increased from 79kW to 88kW. Although the engine power has improved, the two engines still retain the fuel-saving characteristics. 1.3L manual comfort version has a fuel consumption of 4.9L when driving at a constant speed of 90km/h under standard urban road conditions, and 1.5L version has a fuel consumption of 5. 1L when driving at a constant speed. ..
