Maintenance of Diesel Engine Coolant Systems

It is estimated that the failure of an engine coolant system is one of the key factors for the engine downtime. The diesel engines today emit more heat than their predecessors, requiring better cooling mechanisms than ever before. They require a fully formulated, premixed, glycol based coolant containing a heavy duty additive package and de-ionized water. The coolants play an integral role in the system maintenance. They have to face multiple conflicts with rust, acid, foams, debris etc. to maintain the right operating conditions of an engine. Coolants may differ according to the job and requirement. They need to be monitored frequently to ensure proper chemical balance.

No engine cooling system can be maintenance free. Every component degrades over time and so does the coolant. Various factors such as dilution with water, additives and the invasion of foreign particles entering the cooling system, can all cause a chemical degeneration. Products can get mixed, making testing and servicing difficult.

A coolant can perform well only when it preserves its original composition. The mutated version can cause fluctuations yielding disastrous results for an engine. Fleetguard Filtration provides the most comprehensive cooling system product range with support products that help test, service, and repair cooling system fluid. Mentioned below are various ways in which a coolant system can be taken care of in order to experience less downtime & great efficiency.

Coolant Filtration

A coolant filter is a primary mechanism to remove contamination that enters the cooling system through poor quality water, internal component wear or other inbuilt particulates which are a key cause of pump seal failure. Coolant filters are the most effective solution against contamination of the coolants and are essential to service your coolant and protect it.

Test Strips

Using test strips is like the litmus test used to correctly determine the condition of the coolant. Regular testing can identify trends that may be leading to equipment damage. These strips help determine various factors such as

Overall freeze protection and key inhibitor quantity levels.
Overall Quality of the coolant to determine whether it is fit for continued use or is contaminated.
Water Quality – is this water suitable for use in a cooling system.

Refractometers

Depleting glycol levels in the coolant will bring down the boiling point and have a detrimental effect on the engine, especially in hot spots around the head. Refractometers are a near accurate tool to measure the glycol content of engine coolant. It is essential to maintain glycol levels within the specified limits. Different products may require different refractometers depending on their additive makeup.

Fleetguard Coolant Solutions

There are many products available in the Fleetguard range to assist with Cooling System maintenance:

• Ethylene Glycol (EG) and Propylene Glycol (PG) based Fully Formulated Coolants (ES Compleat)

These glycols are available as pre-mixed products, using de-ionized water, which are ready to use. They are also available in the more traditional, concentrated format which requires dilution with good quality water before use.

• DCA (Diesel Coolant Additive) heavy duty corrosion inhibitor

These inhibitors are available as a liquid concentrate to allow initial charging of a standard antifreeze product or to re-charge. A coolant which is low in inhibitor levels.

• Cooling System flushing/cleaning agents to remove scale, corrosion products, oil and gel contamination etc. Radiwash This not only removes contamination /scale/rust in the intricate passages of the engine without need of dismantling but dramatically brings the engines at operating temperatures.

Fleetguard is one of the leading Automobile Filter Manufacturers in India.

CUMMINS FUEL-AGNOSTIC ENGINE PLATFORM DELIVERS LOW-TO-ZERO CARBON FUEL CAPABILITY

GxMedia — Sat, 18 Mar 2023 19:09:33 +0000

Heavy-Duty Hydrogen, Natural Gas And Advanced Diesel Engines To Align With Tier 5

Cummins Inc. (NYSE: CMI) showcased its new fuel-agnostic 15-liter engine platform with hydrogen, natural gas and advanced diesel engines offering low-to-zero carbon fuel capability. The next generation engine is designed to accelerate the decarbonization of heavy-duty off-highway applications.

“Cummins’ all-new platform takes internal combustion to a new level, capable of meeting future ultra-low emission standards, such as EPA Tier 5 and EU Stage 6, together with a low-to-zero carbon fuel capability to help put construction and quarrying sites on a lower cost path to decarbonization,” said Antonio Leitao, VP Global Off-highway Engine Business.

The new engine is a clean sheet design that points to the future of diesel: more capability with less environmental impact. Its high power density sets the standards for heavy-duty performance in key off-road applications including excavators, wheel loaders, drilling rigs, road planning, milling machines, haul trucks and air compressors. Innovatively designed hardware provides lower weight with maximum engine durability, even when working on the most challenging jobs

The fuel-agnostic architecture of the 15-litre platform utilizes a common base engine with cylinder heads and fuel systems specifically tailored for it to use carbon-free hydrogen or biogas with up to a 90 percent carbon reduction. Cummins’ 15-liter hydrogen has ratings up to 530 hp (395 kW) and natural gas up to 510 hp (380 kW). The advanced diesel version can use either sustainable HVO fuel or biodiesel with ratings up to 650 hp (485 kW) for the most demanding off-highway duty-cycles.

“The 15-liter has a significant increase in power density with a more compact installation envelope providing equipment manufacturers with the capability to do more with their machines,” added Leitao.

A key design feature of the new platform is a Double-Overhead-Camshaft (DOHC) realizing significant advances in combustion and thermal efficiency. Friction losses across the engine design have also been reduced and a sculpted block contributes to weight saving. The DOHC design also enables a more efficient integral engine brake to be accommodated.

Next Generation 15-Liter Engine

The 15-liter hydrogen engine with direct-injection, lean-burn combustion will be available with ratings from 400-to-530 hp (298-395 kW) and a peak torque of 2600 Nm. Running on zero-carbon green hydrogen, it can use a 700-bar pressure high-capacity fuel storage system for maximum operating hours between refueling.

The 15-liter advanced diesel features Cummins latest XPI ultra-high pressure fuel injection system and will offer a broad power range of 450-to-675 hp (335-503 kW) with an impressive 3000 Nm peak torque. Using B100 biodiesel enables up to a 70 percent reduction in carbon and using HVO renewable fuel achieves up to a 90 percent reduction.

For applications powered by renewable biogas, the 15-liter natural gas will offer ratings extending from 400-to-510 hp (298-380 kW) with a peak torque of 2500 Nm available. Very low noise is a further benefit of this engine, particularly for when operating in urban areas.

“Moving forward, our aim is to offer the same agnostic capability across the next-generation of our current 6.7 liter and 9 liter engine platforms,” concluded Leitao.
