Why Are Engine Hours Important + How to Optimize It [2024]

Written by eLogii | Nov 12, 2024 1:45:52 PM

If you run a delivery company or manage a fleet of vehicles, you know how crucial it is to keep your trucks moving and avoid downtime.

Taking care of your engines is a big part of keeping your vehicles in great condition. But how do you keep up with all the maintenance?

This is where engine hours come in.

Engine hours show how long a vehicle’s engine has been running, even when the truck isn’t moving.

By tracking engine hours, delivery managers can monitor vehicle wear and tear. It also helps them set up maintenance schedules ahead of time, prevent breakdowns, and help vehicles last longer.

If you manage a fleet of diesel work trucks or are looking to buy a used cargo van with telematics, engine hours play a big role in planning maintenance schedules.

In this article, we’ll explain why tracking engine hours is important for delivery companies, show you how to calculate them for your vehicles, and discuss other key details you should know to keep your vehicles in great shape.

Read on to find out how engine hours can help you stay on top of engine maintenance.

What Are Engine Hours?

Engine hours show how long an engine has been running—whether over its entire life or during a specific period—even if the vehicle is just idling.

This information is really helpful for delivery companies to track. It helps you track wear and tear on your vehicles.

To measure engine hours, you’ll need an engine hour meter. Mechanical meters are placed in the engine’s flywheel housing. On the other hand, electronic meters use sensors to track engine activity.

Engine hours can be influenced by several factors. These include idling time, frequent starts and stops (which can be tough on delivery drivers), and carrying heavy loads.

That’s why it’s essential to track engine hours and plan maintenance around them—not just around mileage.

Keeping track of engine hours can save businesses a lot of money. Namely, it helps to prevent breakdowns and extend the life of their vehicles.

It also helps with warranty coverage, boosts resale value, and can even support compliance in certain industries.

To get the most out of this data, you should:

  • a) know how to access your engine hours and;
  • b) use it to improve your team’s efficiency, saving money along the way.

Now that we understand what engine hours are and why they matter for delivery companies, let’s dig into how to measure them.

How Can You Measure Engine Hours?

An engine hour meter usually connects to the ignition system and starts tracking hours as soon as the engine is turned on.

But how do these meters actually keep track of engine hours?

Here’s the catch: an “engine hour” isn’t exactly 60 minutes.

💡 Engine hours are measured by counting crankshaft rotations (called tach time) instead of by regular clock time (known as Hobbs time).

This means one engine hour could be longer or shorter than an actual hour. This depends on the engine’s RPM (revolutions per minute).

Types of Engine Hour Meters

Tracking engine hours manually with pen and paper is a thing of the past. Today, delivery managers can use digital tools to keep track of engine running time.

Here are some digital ways to monitor engine hours:

  • GPS Management: One common way is with a GPS platform. It uses hardwired or plug-and-play GPS devices to track when a vehicle is on, how long it runs, and its location. This data is available on a computer or mobile device, making it easy to monitor vehicles in real time.
  • Hour Meters: Another option is hour meters. It connect directly to the engine and track only its usage. Some advanced tracking systems also include features like real-time monitoring and driver behavior tracking.
  • Electronic Logging Devices (ELDs): ELDs are popular for delivery vans. They track engine hours along with mileage and fuel use. ELDs also monitor overall engine health but often come with a monthly subscription fee.
  • Odometers: If a vehicle doesn’t have an hour meter or ELD, you can use the odometer as an estimate for engine hours. Although less accurate, it still provides a general sense of engine usage.

Next, let’s look at how to put your engine hour readings to use.

How to Calculate Engine Hours

Calculating engine hours—whether for a vehicle’s lifetime or a recent trip—is simple and only takes a few steps:

  1. Locate the Hour Meter: The hour meter is typically on the dashboard or instrument panel. If your vehicle has telematics or GPS tracking, you can also view engine hours through the software.
    • For instance, let’s say you want to check the engine hours of a van using a GPS management system. You would log in to the software and go to the engine hour meter section to see the readings.

  2. Note the Starting Reading: Record the hour meter reading at the start of the most recent period you’re tracking.
    • For example, if the starting reading is 3,450 hours, make a note of it.

  3. Note the Ending Reading: At the end of the period, record the new hour meter reading.
    • Let’s say the ending reading is 3,465 hours. This is the vehicle’s total engine hours up to this point.

  4. Calculate Engine Hours for the Period: Subtract the starting reading from the ending reading to find the engine hours for that time period.
    • In this example, you would calculate 3,465 - 3,450 = 15 engine hours.

Keep in mind that engine hours don’t always match miles driven. For example, if a vehicle spends a lot of time idling or running at low RPM, it can rack up engine hours faster than miles.

What Affects Engine Hours?

Let’s look at a few factors that can impact engine hours and see how you can help your delivery team work more efficiently:

  • Usage: This one’s simple—the more you run an engine, the more RPMs and engine hours it accumulates. Both driving and idling count as engine time since both generate RPMs. Also, certain add-ons, like Power Take-Off (PTO) units that use engine power to run extra equipment, can add to engine hours.

  • Load: The weight of your cargo affects how hard the engine has to work, how fast the crankshaft spins, and how quickly engine hours build up. It’s good to keep this in mind when planning routes and scheduling deliveries.

  • Maintenance: How well you maintain your engine also plays a big role. Regular tasks like changing air filters, fuel filters, and oil, as well as doing tune-ups and inspections, can help the engine run smoothly, keeping RPMs and engine hours down.

  • Environment: Extreme temperatures, dust, and other factors can make the engine work harder, causing engine hours to go up more quickly.

  • Age: Engines naturally wear out and become less efficient over time. As an engine ages, it may need to work harder to get the same jobs done, adding to engine hours. Tracking engine hours can help you know when it’s time to replace the engine or retire a vehicle.

Why Engine Hours Matter for Your Business

Here’s a quick look at why keeping track of engine hours is smart for your business:
