The Air inlet system is essential for maintaining engine health, reducing wear, and ensuring your HOWO A7 8X4 operates at peak performance in all conditions.
The Air filter assembly is the primary filtration unit that removes dust, dirt, and contaminants from incoming air. It features a high‑capacity paper element with a safety filter, ensuring that only clean air reaches the engine. The housing is manufactured from impact‑resistant plastic with a corrosion‑proof coating, and the seal is designed for a tight fit to prevent unfiltered air from bypassing the filter element.
The Damping pad is a resilient rubber mount that isolates vibration from the air filter assembly to the chassis. Manufactured from high‑grade elastomer, it absorbs engine and road vibrations, reducing noise and preventing premature wear of the mounting hardware. Its precise fitment ensures that the air filter remains securely in place without transmitting harshness to the cab.
The Hex bolt is a high‑strength fastener used throughout the Air inlet system to secure brackets, the air filter, and ducting. Manufactured from grade 8.8 steel with a corrosion‑resistant coating, it provides reliable clamping force and resistance to vibration. Multiple lengths and diameters are included to accommodate different mounting points, ensuring a secure and vibration‑proof assembly.
The Steel pipe is a rigid metal conduit that connects various sections of the air intake ducting. It is manufactured from high‑strength steel with a protective coating to resist corrosion and abrasion. Its precise bend and length ensure accurate routing of the intake air, minimizing pressure drop and maintaining airflow velocity.
The Rubber pad is a flat elastomeric cushion placed between metal components to prevent chafing and reduce noise. Manufactured from durable EPDM rubber, it provides a soft interface that dampens vibration and prevents metal‑to‑metal contact, protecting both the air intake components and the chassis.
The Washer is a large‑diameter flat washer that distributes clamping load evenly under bolt heads and nuts. Manufactured from steel with a zinc‑plated finish, it prevents damage to mounting surfaces and ensures a secure, rattle‑free connection. Its wider surface area is essential for applications where high clamping forces are required.
The Type 2 all‑metal hex lock nut is a prevailing‑torque lock nut that provides a secure, vibration‑proof fastening. Its all‑metal construction ensures excellent temperature resistance and durability, making it ideal for critical chassis and engine bay connections where loosening due to vibration is a concern.
The Air filter bracket assembly is a sturdy steel frame that securely mounts the air filter to the chassis. Manufactured from high‑strength steel with a corrosion‑resistant coating, it provides a rigid platform that maintains the filter’s position and prevents movement under extreme conditions. Its precise bolt holes ensure accurate alignment and easy installation.
The Spring washer is a split‑helical locking washer that provides preload and prevents loosening of fasteners under vibration. Manufactured from high‑carbon spring steel, it maintains tension on the bolt, ensuring that all connections remain tight even under the high‑vibration environment of the engine compartment.
The Flat washer is a standard flat disc used to distribute load and protect the mounting surface from damage. Manufactured from steel with a protective coating, it provides a smooth bearing surface under the bolt head, reducing friction and preventing galling during tightening.
The Rubber hose 104 is a flexible, reinforced rubber tube that connects various rigid sections of the air intake system. Manufactured from oil‑ and heat‑resistant elastomer with a textile reinforcement, it withstands the high temperatures and pressures of the engine bay while providing a leak‑tight seal. Its flexibility allows for easy routing around obstacles.
The Air inlet duct (after filter) is a rigid plastic or metal conduit that channels filtered air from the air filter housing to the engine intake manifold. It is precision‑formed to ensure smooth airflow with minimal turbulence, and its internal surface is smooth to reduce pressure drop. The duct is secured with clamps and brackets for a leak‑proof connection.
The Air inlet duct (before filter) is the intake pipe that draws ambient air from the grille or snorkel into the air filter. It is designed to capture cool, fresh air while preventing water ingress. Its internal design promotes laminar flow, reducing the restriction on the engine’s intake system and improving volumetric efficiency.
The Lower air inlet duct is a secondary duct that routes air from the lower front area to the main intake path. It is typically used in conjunction with the primary duct to provide additional airflow capacity, especially under heavy load conditions. Its robust construction resists deformation and ensures consistent air delivery.
The Lower air inlet duct bracket assembly is a structural support that secures the lower duct to the chassis. Manufactured from high‑strength steel with a corrosion‑resistant coating, it ensures that the lower duct remains properly aligned and does not vibrate or rattle, maintaining a quiet and efficient air intake system.
The Air inlet pipe bracket is a mounting clamp that holds the air inlet duct securely to the cab or frame. Its adjustable design allows for precise positioning, and its rubber‑lined interior dampens vibration and prevents wear on the duct surface. This bracket is essential for maintaining the integrity of the intake system over time.
The Dual‑tube cyclone air inlet assembly is a high‑performance intake component that uses cyclonic action to separate heavy particles from the incoming air before it reaches the filter. This pre‑cleaning process extends the service life of the air filter element and improves overall engine protection, especially in dusty environments.
The Manual air filter cover indicator switch is a monitoring device that provides a visual or electrical signal when the air filter requires servicing. It senses the restriction level across the filter element and triggers a warning light on the dashboard, allowing the driver to proactively replace the filter before performance is compromised.
The Rubber hose 210‑150 is a specialized flexible conduit designed for specific routing requirements in the Air inlet system. Its dimensions and material are tailored to withstand high temperatures and vacuum conditions, ensuring reliable air delivery without collapse or leakage.
The Hose clamp 180/230 NIS670 is a heavy‑duty band clamp used to secure flexible hoses to rigid ducting or fittings. Its wide range of adjustment and robust construction provide a leak‑tight seal that resists loosening under vibration and thermal cycling. The clamp is designed for easy installation with a screwdriver or nut driver.
The Rubber block is a solid elastomeric mount used to support and isolate heavy components such as the air filter or ducting. Its durable construction absorbs vibration and prevents metal‑to‑metal contact, contributing to a quieter and more durable Air inlet system.
The Cover is a protective cap that seals unused ports or openings on the air intake components. Manufactured from durable plastic or rubber, it prevents dirt and moisture from entering the system when not in use, and it provides a finished appearance to the assembly.
