The motorcycle of choice in the early decades was the Harley Davidson 45 cubic inch model due to its high torque at low rpms similar to farm engines.

During the early 1970s, Mobil ran a TV commercial featuring a character known as " Mr. Dirt " to show the ruinous effects that dirt had on automotive engines for which a tank of Mobil Detergent Gasoline could provide a cure and preventive medicine against damage that could lead to costly repairs.

As automakers were switching en masse from carbureted to fuel injected engines during the early to mid-1980s, the detergent additives that existed in most available gasolines proved not to be enough to prevent injection clogging, leading to drivability problems, Mobil received accolades from General Motors and other automakers for increasing the detergency of its Super Unleaded gasoline in 1984 to prevent formation or deposit build-ups of the injectors but also remove existing deposits as well in normal driving.

People discussing magnetos and coils used in early internal-combustion engines generally used the term " tension " instead of the more modern term " voltage.

Some aviation engines as well as some early luxury cars have had dual-plugged systems with one set of plugs fired by a magneto, and the other set wired to a coil, dynamo, and battery circuit.

A few early gas engines had double-acting cylinders, but otherwise effectively all internal combustion engine pistons are single-acting.

Balzer's early designs even dispensed with cooling fins, although subsequent rotaries did have this common feature of air-cooled engines.

Historically, thermodynamics developed out of a desire to increase the efficiency of early steam engines, particularly through the work of French physicist Nicolas Léonard Sadi Carnot ( 1824 ) who believed that the efficiency of heat engines was the key that could help France win the Napoleonic Wars.

Again among those jubilantly reunited bunkmates, I was shy with Jessie and acted as I had during those early Saturday mornings when we all seemed to be playing for effect, to be detached and unconcerned with the girls who were properly our dates but about whom, later, in the privacy of our bunks, we would think in terms of the most elaborate romance.

During the early part of this century, the Brown & Sharpe works in Providence were unchallenged as the largest single manufacturing facility devoted exclusively to precision machinery and tool manufacture anywhere in the world.

Its early morning patrons were coachmen, who fortified themselves for the day with that delicacy.

Eight years ago while we were going through the mud-sweat-and-tears construction period, we were each solaced by the vision of early morning dips and evening home-comings to a cool family collected around the pool with a buffet table laid out nearby for the lord and master's delectation.

The early works were conceived for a sophisticated, international audience ; ;

Because of the authentic homogeneity of his early Nationalistic materials, and his flair for orchestrations -- his brilliant Petruchka, his savage Sacre Du Printemps, his incisive Les Noces -- the world kept hoping that he could recapture the historical direction for which his native talents were predisposed.

He worked in oil for years before beginning his work in watercolor, and his first public recognition and early honors, including his election to the Academy, were for his essays in the heavier medium.
