Automotive engine blocks and cylinder heads feature intricate structures filled with water channels, oil galleries, threaded holes and enclosed cavities. After die casting and machining, cutting fluid, aluminum and iron metal chips, release agents and carbon deposits tend to remain trapped inside. Substandard cleanliness directly leads to engine abrasion, oil leakage and pipeline blockages. Barker develops an exclusive integrated cleaning solution for engine blocks and cylinder heads of passenger vehicles, heavy-duty trucks and range extenders for new energy vehicles, fully complying with ISO16232 and VDA19 cleanliness standards for auto components.

This solution centers on numerically controlled high-pressure pulsed water cleaning technology paired with multi-directional rotating spray assemblies. The equipment precisely reaches deep and shallow passages of blocks and heads to flush dead corners inside cavities, thoroughly stripping stubborn grease and metal debris in a single process. An integrated ultrasonic pre-cleaning module softens carbon deposits in thread crevices and tiny bores, while high-pressure water jets deliver deep cleaning to eliminate common drawbacks of conventional cleaning such as residual contaminants and uneven cleaning inside passages.

The fully automatic closed-loop production line covers robotic automatic loading and unloading, rough cleaning and residue removal, ultrasonic soaking, multi-stage pure water rinsing, vacuum hot air drying and circulating wastewater filtration. The fully enclosed system prevents wastewater overflow and seamlessly connects to engine machining lines for non-stop 24-hour mass production. Its intelligent control system is compatible with factory MES platforms, recording real-time parameters including water pressure, cleaning duration and water temperature to enable full traceability of cleaning data and meet quality audit requirements of vehicle manufacturers.

The solution balances environmental performance and production costs, equipped with multi-stage oil-water separators and metal chip recovery units. Filtered cleaning water is recycled, with over 98% of cleaning agents recovered. The low-temperature cleaning process avoids oxidation, rusting and deformation of cast iron and aluminum alloy blocks and heads. Cleaned components feature dry passages and spot-free surfaces, with particulate contaminants consistently controlled within OEM standards. Delivering superior cleanliness, high automation and low maintenance costs, Barker’s cleaning solution safeguards the production quality of core engine parts and effectively reduces post-production engine failure and rework rates.
