Pressure Washers Make A Clean Engine Bay

Simple preventative measures can go a long way in warding off engine compartment fires.

In May 2019, the National Heavy Vehicle Regulator (NHVR) held its first heavy vehicle fire roundtable in Brisbane. It was a result of an ongoing investigation following a series of fires last year involving primemovers. The regulator announced its plans to release a series of safety bulletins to help raise awareness of the common fire risks that have been identified in the probe and to outline the actions required to help mitigate the risks.

NHVR executive director of safety standards and assurance Geoff Casey said the May roundtable, which brought together leading forensic fire investigators, fire service officials, police and members of the heavy vehicle industry and supply chain, was aimed at identifying causes and preventative actions.

The NHVR bulletin identified a number of common fire risks in heavy motor vehicles, predominantly:

shorting of electrical cables and connectionsinappropriately rated electrical componentsfuel line failuresheat generated by a turbochargerengine bay maintenanceIt also outlined preventative actions that operators should undertake, including:reviewing the common causes of fires and identifying those that may be present in their fleetreviewing maintenance management systems to remove or reduce any risk factors, and improve the safety of their transport activitiesensuring those who carry out servicing or modification on higher-risk components or systems on their vehicles, such as electrical systems, have measures in place to verify that fire risks are not introduced.

Spitwater, one of the leading Australian manufacturers of high pressure water cleaners, talks to Owner//Driver magazine about one of the most common fire risks in heavy vehicles and how to prevent it.

“Engine compartment fires are a reality,” Spitwater director Gary Rodgers says. “However, some simple maintenance and cleaning can prevent this from happening.” Rodgers shares a few tips that can help reduce the risk of such fires, including:

keeping the engine and the engine compartment clear of fuel and oil residue through regular cleaningidentification and timely repair of fuel and oil leaksmaintaining efficient electrical connectionscarrying out regular checks for leaks and wiring condition.

THE IMPORTANCE OF A CLEAN ENGINE BAY CANNOT BE OVERSTATED.

The importance of a clean engine bay cannot be overstated. But not everyone has the proper knowledge how to perform this important task. Spitwater has outlined a step-by-step cleaning method that can help you maintain a clean engine bay:

•Prepare your pressure washer, degreaser and applicator for action

•Allow the engine to cool before cleaning as applying chemical or water to a hot engine can create problems, particularly electricals

•Fasten or remove any loose items such as covers or guards to avoid damage from chemical or water

•Disconnect the negative terminal on the battery – this will help protect electrical components from being damaged by water

•Use plastic bags or wrapping to cover any sensitive areas including ECU’s or air intakes

•Spray the engine and surrounds with degreaser using an applicator sprayer or soft brush to assist the cleaning before applying any water

•Depending on the grime level allow between three minutes to 20 minutes dwell time for the degreaser to work, and repeat the process if necessary

•Clean off using your pressure washer and then pass over once more for a final rinse avoiding any sensitive areas.

Spitwater says this simple method can go a long way in preventing engine compartment fires. While any pressure washer can be used for this task, Spitwater says using a hot water pressure washer will produce the best results. It also recommends using a good quality degreaser such as Nerta Super Degreaser. The degreaser must be applied with a pump up sprayer for best results.

Why We Use Interpump
For over 30 years, Spitwater has used only one make of pump in its high pressure washer range: the Interpump pump, produced by the Interpump Group. INTERPUMP – THE WORLD'S LARGEST MANUFACTURER OF HIGH PRESSURE PUMPS Based in Italy, Interpump Group S.p.A. is the world's largest manufacturer of high pressure pumps. The company was founded in 1977 as an ambitious project by the company’s founder, Mr Fulvio Montipò and was based on his vision about designing and building pumps that were more compact, quieter and easier to service. As his vision developed, Mr. Montipò, introduced substantial technical modifications to the product, including innovations such as use of full-ceramic pistons, which ensured a higher degree of overall pump reliability. This revolutionary design enabled the Interpump Group S.p.A to achieve the worldwide leadership from the early 1980's, with the company becoming the recognised reference point for the high-pressure pump industry and even for its competitors. The Interpump Group leadership has strengthened throughout the years mainly thanks to unparalleled quality standards, guaranteed by total control of the production process, starting from raw materials up to the finished product. INTERPUMP BRANDED AS GENERAL PUMP FOR THE US MARKET Interpump Group today manufactures pumps with pressure up to 500 Bar with 75% of its production destined for export all around the world including to the US, under the brand name of General Pump. In addition to this, the company has expanded its range of products through strategic acquisitions of brands such Pratissoli, the leader in the ultra-high pressure pump market. Unfortunately, like with everything these days, there are some common misspellings for Interpump, usually written in the two word forms and including: inta pump, as well as inter pump and intapump. However, the product should always be correctly referred to in singular form: Interpump. INTERPUMP – THE HEART OF ALL SPITWATER HIGH PRESSURE WASHERS Spitwater and the Interpump Group have grown together and are intrinsically linked, benefiting from each other’s experience in this highly competitive industry. As the world becomes smaller with the globalisation of markets, it is reassuring to know that Spitwater is the official distributor of the Interpump pumps and components in Australia. Spitwater exclusively chooses Interpump for the supply of high pressure pumps in it’s Australian manufacturing of high pressure cleaners. This partnership is delivering to Spitwater customers all the experience and strength of the giant Interpump Group in the heart of every Spitwater high pressure water cleaner. SPITWATER - PROUD OF ITS FIRST CLASS PARTNERS One of the areas that sets Spitwater pressure washer products in front of its competitors is its strategic alliances with industry leaders like Interpump, Honda, Kubota and PA Products.

Hitachi Construction Equipment
The Problem Hitachi Construction Equipment have a large range of excavators and plant equipment for sale, hire and service.  They have two sites providing excellent coverage to the Melbourne CBD and surrounds. Being able to present equipment to hire clients clean and professional is key.  Their own Service Department need to clean so as they can access parts and conduct servicing. They have to clean big, fast & cost effective when dealing with heaps of caked on clay and debris. The Solution Having used a Spitwater hot wash 3 phase unit before – they invested in a larger model to increase the water flow and pressure.  The SW2021 at 21 lpm and 3000 psi was just the right unit.  They also invested in using the SUTTNER KW fittings for easy lance and foaming change over. The Benefits With water flow being KING the increased flow that this machine has provided - wash bay times have come down by around 25%. Improved wash bay through put has allowed for increased machine hire units ready to go out with no hold ups. The same solution was rolled out at both sites, making it easy for driver & operator to use the same units and set up when working at either site. The new units have been set up with a PM Program allowing for maximum machine up time.  Hitachi need the wash bay operational at all times.
