I am 4JB1, an old engine that will never retire

2025-07-22

Hello everyone, my name is 4JB1 Engine, I am a "veteran" in the excavator industry. I debuted early, played steadily, and had strong output. I heard that young engines now focus on "intelligent energy saving"? Sorry, my main focus is "just do it"!

🧓"I'm old, but I don't have Alzheimer's!"
Someone said: "How many years has 4JB1 been used? Is it still in use?"
I laughed. I'm an engine, and I've lived longer than your father's Nokia - but I'm not a slacker!

I'm not bragging. Half of the old excavators still in operation on the market are supported by my old face - shaking every day, but still making you money!

💪"I don't compete on appearance, I compete on durability!"
Today's engines have plastic shells and electronic control systems, and even start-up requires a password.
Me? A pure mechanical man, no pretense or show-off, a key "squeaks" to ignite, and you can go to work after three beeps!

Don't ask me if I have an "intelligent system" - my greatest "intelligence" is: less damage, fast repair, and high torque!

🛠️"I'm not high-tech, but I'm high-output."
Once an excavator was installed with me, and it worked for three consecutive years without moving to the maintenance room. The masters on the construction site all called me "4JB1, a cow that never leaves the ground!"

Once, a young engine said that I was "outdated in technology", and as a result, I "suffered from water and heat decay" in less than half a year. I watched it go into the factory for repairs, and said silently in my heart:

"It's still me, a rough guy, who knows what it means to do practical things."

😂 Real quotes from the construction site
👷‍♂️"What's the engine of this car?"
👴"4JB1, old friend, it's been running for 30 years."
👷‍♂️"Is it still in use?"
👴"Not only is it in use, it's still working, unlike the one you use, which has a fault code every day!"

I am 4JB1, not fancy, not hypocritical, not spoiled,
You give me oil, I will give you strength-
Construction site brothers push for life!

My boyfriend is a 4JG1 engine, he is strong and stable and doesn't make any noises

Confession of the 4HK1 engine: I’m the top star on the construction site. I don’t allow you not to know me
