The deploymentMach electric hybrid DH-i hybrid systemofA 4-speed electric hybrid SUV- Dongfeng FengshenHaohan DH-ISince its launch, attention and sales have soared sharply, quickly dominating the list, becoming the hybrid marketThe benchmark model。The Haohan DH-i, which is sold from only 100,000 yuan, is quite cost-effective, so what about its internal materials?Today we take a look at its chassis and interior.
Click ***Chassis: Flat
The chassis is fairly flat, there are no protruding parts, and there are plastic guards under the engine.
The front drive shaft is an equal-length half-shaft design, equipped with a transition shaft, and the connecting bearings of the transition shaft are equipped with heat-insulating aluminum tiles, and the workmanship is very meticulous. Although there are no guards on both sides of the chassis, the high-pressure lines are protected by plastic boxes, and the exhaust insulation is mostly intact.
The resin fuel tank is from Peugeot Citroën and is insulated with aluminum tiles near the exhaust pipe.
Front suspension: MacPherson
The front subframe is a one-piece structure. The front overhang is a common MacPherson construction, with a single-layer stamped steel plate lower swing arm with an additional piece of reinforcement.
Rear suspension: four-link
The rear subframe is a full-frame knot. The rear suspension is the current mainstream four-link structure independent suspension, the standard "three horizontal and one vertical", 100,000 yuan in this level, such a rear suspension is rare, let alone a hybrid SUV.
The rear suspension adopts a spring barrel separation structure, which improves the comfort of the vehicle to a certain extent.
Door structure: stamped hinge, welded door
Door hinges are more common stamped hinges, and the doors are welded half-frame doors.
Soundproofing cotton: large area
The door trim panels were removed and plastic waterproof membranes were used, and large areas of white virgin acoustic insulation were pasted on the door trim panels.
Side impact beam: round tube
There is a circular side impact beam in the front and rear doors, and a stiffener in the rear door.
Rear seats: with steel plates
This hybrid SUV with a minimum price of 100,000 yuan actually has a complete steel plate in the rear seats.
Rear headrests: No headrests
The headrests of the rear seats** are sponge blocks, and the headrests in the other two positions are not adjustable, but they are supported by a skeleton inside.
Flooring: tightly wrapped, **flooring
The large line is wrapped with better quality cloth tape, which is relatively tight. The floor soundproofing is two-layered, the lower layer is **cotton material, and the upper layer is carpet. As for the amount of formaldehyde released, it needs to be measured with professional testing instruments.
Through testing, the formaldehyde emission in the floor was measured at 0058 milligrams per cubic meter, the formaldehyde emission of the seat is measured at 0012 milligrams per cubic meter, the formaldehyde emission in the roof is measured at 0047 mg per cubic meter. （ps.This test is relatively extreme).
Interior air
In order to more accurately detect the amount of formaldehyde emitted from the air inside the car, the air inside the car was tested by "pump sampling" and "phenol reagent spectrophotometry". This test method is the formaldehyde test method currently used by formal testing institutions.
Test Method:The test vehicle will be placed in a natural environment with the doors and windows open for full ventilationSubsequently, a silicone hose is fixed near the driver's headrest to simulate the human breathing positionClose the doors and windows and park the vehicle in a constant temperature of 23 1 for 16 hoursUse a sampler to suck out 10 liters of car air from a hose pump and react with the phenol reagent;Drop the chromogen into the phenol reagent and let it stand for 15 minThe aldehyde n-formaldehyde detector was used to test the colored samples and obtain the results.
After 16 hours of containment at a constant temperature of 23 1, the car's formaldehyde emissions from the interior air measured at 0040 mg per cubic meter.
In addition to formaldehyde, TVOC is also an important toxic and harmful gas, which is one of the main reasons for the strong smell in the car. TVOC refers to the general term for all organic gaseous substances in space, such as benzene, alkanes, aromatics, alkenes, ......These organic substances can cause harm to human health.
Test Method:The test vehicle will be placed in a natural environment with the doors and windows open for full ventilationSubsequently, a silicone hose is fixed near the driver's headrest to simulate the human breathing positionClose the doors and windows and park the vehicle in a constant temperature of 23 1 for 16 hoursThe MP181 TVOC detector was used to suck the air in the truck from the hose pump until the value was stable, and the final result was obtained.
After 16 hours of containment at a constant temperature of 23 1, the vehicle's in-cabin air VOC emission measurement was 039 mg per cubic meter.
The front suspension swing arm of this Dongfeng Fengshen Haohan DH-i has increased reinforcements, and the rear suspension uses a standard "three horizontal and one vertical" four-link independent structure, even the joint venture cars of the same level can not see such a rear suspension, and many of this price level are still using torsion beams.
After 100,000 kilometers of testing, there was no cracking or oil leakage in the chassis rubber sleeve, shock absorber barrel, or other oil seal components. There is no abnormal noise in the interior part, and the test results of formaldehyde and TVOC emission are also good. Therefore, this 4-speed electric hybrid SUV Haohan DH-i, which is sold from 100,000 yuan, is worth the price and is worth buying.
The conclusions and opinions of the measurement data in this article and ** are only responsible for this vehicle, and the measurement data are responsible for the published experimental methods. ）
